Thanks! I called Ideal and they said I probably had the heat too high for them in their coop. It's already getting hot here in Texas, so now I took out the heat lamps and hopefully they'll get the rest of their feathers soon now that I did that. I did notice a few little feathers coming in around the necks of some of them today. And I also noticed a few of the ones I thought were WFBspanish are actually black cochin bantams that also haven't feathered much yet. I guess they were getting too hot too! It's funny though the standard size cochins are super fluffy all over, and they've all been in there together! Overall the birds are all very healthy though so no complaints. I just noticed the difference in the feathering since they're all the same age and some look quite different than others.
