thats interesting, thanks for sharing, cant recall having issues with my hens and crop's, i alternate egg shells and sometimes oyster shells, but always available for them at will. The paint on the left is a TW mare, the paint in the middle is prolly the one your referring to is a black and white paint cross between quarter horse mare and Arabian stallion, he has the 1/4 horse natural muscling and is on the smaller side, he has the dish cheeks, spunky fellow, the Sorre/Chest nut on the far right is a thouroughbred, all my horse are have been rescue horses, we lucked out with these, great horses, took a while to turn em aound though.
