none of my colts feet had the foal slippers that bad..
they had some but came off very quick.
the premie i had though, they looked like that a lot. he would *try* to stand, kinda seemed like a dummy foal.
he was very small, 40 pounds, if you tried to stand him up his legs would cross/buckle and he'd fall. suckle reflex was intact. but legs were definitely not finished developing [the bones/joints.]
Don't know if this one was born early/late on time though. if it was on time then, I have no idea o.O
