That's what happens when you get chicks from a hatchery.
These are Silkies I got from Ideal. They may not look like it, but they are crested, though they are small and not full like show quality birds. Also, they don't have vaulted skulls.
Sultans for sure. Looks just like what my chicks used to look like. (They are about 4 weeks old now).
I don't think sultans get very broody. They are an ornamental breed. Every website I've read said they only lay an egg about once a week and they aren't broody. Though mine like to act all motherly to the younger chicks.
My sultans have the 5th toe and feathers on outside of leg and outside toe, not all the toes like some of yours seem to. I don't know for sure, put they are cute.
100% they are SULTANS. They have the works, beards, muffs, 5 toes/foot, foot feathering, pink skin, v combs, and vulture hawks. Very cute! I love Sultans!
