My girls are all molting too. It looks like a featherbed exploded in thier coop and run. My poor little Silver Spangled Hamburg is almost nothing but quills right now. I try to give them extra protein this time of year - high protein feed mixed with thier regular feed and BOSS for treats. And I have noticed that they all seem to snuggle at little closer together at night. So I wouldn't be too worried.
Last year one of the girls decided to molt in January when it was freezing outside. Bare butt, chest and neck. But she seemed to do fine, no problems.
My RIR, on the other hand, apparently ended up with a bit of a protein deficiency. She started walking sideways like she was drunk. Scared the heck out of me But I checked in here with all the great folks on BYC, found out she just needed a little more protein than the others, and she was fine.
Don't worry (yeah, right. I know.) Or if you do worry, check in here at BYC. You'll be sure to get all the help and support you need.
Good luck.
