Hey there, everybody! De-lurking from Southeastern Virginia to give some feather regrowing advice.
I've got an Ameracuana pullet that had a rough December in all this snow. She broke a toenail on each foot so it hurt to walk. She's just started walking again this past week. We had a feeling there was an additional foot injury since she didn't want to bear weight on that right foot. "Snowy" also had a bad case of mites. I think this is why all the feathers were missing from her back. (No rough roosters causing the feather loss!)
Snowy is now a trooper when it's bathtime. I end up wearing half the bath water, but she lets me shampoo and rinse her. Suave children's strawberry scent 2 in 1 shampoo makes her smell nice! After a thorough rinse, Snowy looks forward to the blow dryer and heating pad. Need I say she is becoming spoiled?
Over on the heritage breed threads, Bob has mentioned diets and treats to help regrow feathers. Feathers are mostly protein, so a moulting bird needs a little more protein than usual. Snowy is now eating Purina Gamebird Grower. It's 30% protein. Other foods to increase protein for your birds include beef liver, sardines, or tuna. Kitten Chow is supposed to be good. Bob also mentioned one of his mentors fed his show birds sunflower seeds. Iirc, it was 6 seeds each per day for a month prior to the show.
Snowy now is covered in pin feathers. The better diet and quiet time away from the flock has made all the difference. Now a little chick companion is encouraging her to eat more. We know we will see continued improvement if the chick doesn't drive her nuts first. Her mothering instincts kicked in enough that Snowy allowed the chick to snuggle with her, but she draws the line at sleeping in the middle of her back!
Anyway, I hope you are able to help your freezing girl to regrow those feathers quickly! She needs to spend her energy making eggs for you, not trying to stay warm. Take care!
