This is not precisely an emergency, I doubt it's a disease, doesn't seem to be an injury, and probably doesn't have a direct "cure," but I didn't know what other section to post this in, so forgive me: I've noticed in a recent clutch of pullets and cockerels that we hatched (under a hen) and raised (outdoors with the main dual-purpose flock), that a least a few of the young birds are missing toenails on a least one, but usually several, toes. (If it seems odd to you that no one noticed before now, it's because these chicks weren't hand-raised, but were raised by their brood mother, and grew up with the rest of the flock and running all over in a big coop with multiple runs--so I've probably handled each one individually only a few times, and it never would have occurred to me to check that they had toenails!) Anyway, anyone else ever seen this? Is this genetic, environmental, nutritional, the result of a pathogen, or what? None of them seems to suffer for it, and they have no other faults I can see. They are quite healthy and vigorous and behave normally (hence why this wasn't noticed earlier). I'm curious, in part, because from a practical standpoint I'll have to decide soon whether to keep the pullets on to lay/breed (as I had hoped), or whether I'll need to cull.
