I've been working on mottled silkies, and have had a lot of chicks start off with grey legs and completely pink toes - which looked adorable, by the way. So far, all but one have grown out of it, bit by bit, until the pink was only on the very toe tip, and finally the toenail, and then gone altogether. These were all Fm chicks, with blue-grey skin (verified by checking in their armpits).
My one exception is a girl who is both mottled and splash ( mo/mo and bl/bl ). She's just reached egg-laying age, but still has a few pink toe tips and a completely cream colored beak, which looks quite unusual on her face since the skin all around the beak is the typical silkie blue-grey. I will be interested to see how long it takes for all her extremities to melanize - if it happens at all. Two genes which suppress the production of the black pigment, eumelanin, locked in a struggle with another gene (Fm) which tries to overproduce it in all sorts of unusual places... what will the winner be?
