turning into roans??
okay, so the horses are starting to shed out, and some things we've noticed:
my sister's registered black/white, minimum marked tobiano paint gelding now has white hairs throughout his coat all over(except his head and legs) like he's starting to roan. he's 5yrs now. and its like one of his spots has starting running down his butt. its seriously roan looking and like someone smeared wet paint.
and while he's black he has almost a sooty shade about him.
meanwhile my 3yr bay QH/arab has white hairs throughout her coat as well,(except her head and legs) not quite as much as the paint, but very noticable. i don't know anything about her bloodlines, just that she is a QH/arab mix.
she was a black baby, and like a chocolate shaded bay last summer. near black this winter, and from what i can see, her summer coat will be very light, like a light caramel (hmmm wonder if i'm hungry?)
but they both have this roan looking thing going on
my sister was searching around and found some places that said a horse can roan as late as 6 to 7yr and sometimes even later.
Most horses have random white hairs within their coat that don't mean anything. From the sounds of it, the second one is just the random white hairs that are completely normal. Pictures of both would be nice.
Roans are born roans. They don't "roan out" like a gray grays out.
Roans are born roan and would have one roan parents. I think what you are seeing, is possibly some type of sabino coming through. Very typical with tobianos.
okay about half way down, this at least says that roans can be born any color, but unlike grays, have dark heads...
GRAY VS ROAN HORSES: How to tell the difference between gray and roan
"In horses, both true roan genes and grey genes are dominant genes. That is, a horse cannot hide these genes, if it has one [or both] of these genes, it will express and become evident. If it is roan, it has to have a roan parent, and if it is grey, it has to have a grey parent.
Frequently, AQHA registered Quarter Horse are listed as being roan, when they are not roan, but grey. That is because inexperienced breeders can mistake young grey horses for roans, report them as roans to AQHA, and it is recorded that way on their permanent papers.
Responsible roan horse breeders often consider any foal that appears roan born from both a roan and a grey parent, to be grey until proven otherwise (after 3-4 years of age). 50% of the time, they will turn grey. And in some cases - especially horses which are both roan + grey - this cannot be determined conclusively before they are 3 years old.
If you are interested in buying a roan horse, and do not want a grey, make sure neither of its parents are grey. (Remember, the AQHA registration certificate offers no conclusive proof of this, as it is only as reliable as the information reported.)
So, how can you tell a young grey horse from a young roan horse, especially if you do not know the color of its parents?
A grey horse will show greying (white hairs) on its face, in equal or higher density than on its body coat, usually fairly early on. It is progressive, and a grey horse gets whiter each year. Any color horse can inherit the grey gene, but every grey horse will have at least one grey parent.
A true roan horse will have a solid colored head and legs, the dark color legs usually make a stalagmite point up its legs above the knees & hocks, and its roaning (white hairs) will be dispersed over its body. The degree of roaning (amount of white hairs) will vary from horse to horse but will remain consistent over its lifetime to that horse. The roan over its body will vary seasonally, (lightest in spring, medium in summer, darkest in winter). A roan foal is often born looking solid colored. If it is a light color horse, (carrying creme or dun gene) it may not display its roaning until older. The roan foal will show a lot of coat color development with each shedding, but look for slight roaning in its flanks when born, or creamy underpinning, or silver legs. After it sheds once or twice, you should know whether it is roan or not. It may be lighter as a yearling than as a 2 year old, but past that, roan is not a progressive color. When it reaches its permanent adult roan color, it will remain that way throughout its life. A roan horse will always have at least one roan parent."

the paint didn't have any white hairs throughout his body when we got him, at 3yro, but now we keep finding more and more this year as he sheds out more.
for all i know my bay will have more next year like this paint. for all i know, one of her parent is a roan. i literally don't know her bloodlines save for the fact that she is a QH/arab
there are more websites, but for the life of me i can't find them
but what about my bay?
and, at least it was my understanding, that sabino is more common with overos? though possible for this guy, but we can actually trace his bloodlines, no greys, but a good mix of overos and solids
With the shedding process they can look like they are roaning or greying. :D
I have a bay Tobiano mare,Sure she has some sabino thrown in there too:wink:
She looks like she is roaning or Greying when she is shedding her winter coat.When she is all shed she definitely is her regular bay tobiano those white hairs are gone. I post pics in past threads,but will again.:D
They can be born looking roan. They begin to look roan as soon as they start shedding their foal coat. It certainly doesn't take years.
It is more common to find sabino with overo because it is one of the patterns that fall under the overo category. Tobiano itself can cause roaning, but it's usually just in a patch.
Again, we need pictures of these horses to make a better guess.
well with the paint, the patch on his butt is more on the left, but its almost like smeared to the right now too. but he still has it all over his body. and he is a minimum marked paint, so he is mainly black. but white hairs all over his body now, extremely visible. Sister's out taking pictures right now
again, with the paint, minmum markings. and as he sheds more, more and more white hairs show up
It may just be the way that horse sheds. My mare sheds out very dark and sooty looking before lightening back up. However, I won't make any definitive comments until I can see pictures.
