I pledge never to breed my 2 girls Rain & Willow. Why? Because Rain is too old to safely carry and deliver and Willow is just too darn fat! That and I love them too much to risk losing them for a foal that would be unpapered and a mutt.
I can't post pictures from my mac but I pledge to never breed my mare Timeless Abby! I adore her to bits and she has a super sweet personality but... she's a standardbred that used to race and she's kinda dumb... not much of a thinker that one!
But we did actually got an offer to breed her... some guy wanted a foal out of her and he wanted to keep the foal to race... anyway we said no and will never breed her due to we have absolutly no money to do so nor the expirience!
BUT.... I would love to have a cutie little foal one day... not out of her tho.. she's not all that pretty.. I still love her though! <3
As easy as it is to say that, there is always a risk, and many don't want to take that risk. Also, though I've never been involved with breeding a mare, I'm going to guess that there's a lot more involved than just feeding them correctly.
