A Welsh/Arab cross should have a dollface little foal for your son to raise if his prediction is correct.
"Out of the Mouth of Babes", wouldn't it something if he ended up saying "I told you so"
I have this big honkin' TV-sized computer screen but I can't figure out how to get the color adjustments fixed so everything is skewed. Meaning I can partially see my Wallpaper right thru your mare
I can't wait to hear what the vet says but in the meantime, if you'd like to know the really old-fashioned way to tell if there's a baby in there:
Tie a couple pieces of binder twine together or get a huge piece of string.
Measure her tummy just behind where the girth would go. Keep the string not-too-tight and not-too-loose; pay attention to that
Precisely mark where the string meets with a black marker.
Go to the back of the tummy, where it is still round (before it starts thinning down as it curves toward the flank area).
Repeat the measuring process with the same string (paying attention to keep the tension the same as before).
Also make sure to place it in the same direction as previously (your mark should be facing you).
Mark the string, like you did for the front.
Take the string off her and look to see where the two marks are.
If they are within one or two inches of each other, she MIGHT very well be carrying a foal. I have never seen it be wrong, but that doesn't mean a whole lot in this day and age - lol
Do you know the conditions she came from? Did she happen to be in a pen "with her son?" If so, that tummy could really be suspicious.
You got her in April, it can take 10 - 13 months (the average is 11) for a foal to be born, so if she is in foal the vet will be able to tell
