Two of my five chickens have started molting now too! They are just over a year old. In Colorado, our winter really starts in March....so I have two bare chested ladies (A Black Star and an Australorp) who are molting in the cold snap. However, I can't find a feather anywhere! My ladies instantly eat any feather they find floating about.....but luckly they don't hen peck or pull them out of each other. I've been very concerned that maybe something else is wrong. Especially as I've read that egg production goes down when they molt...but my ladies are ridiculously consistent...even through the winter and I didn't provide any artificial light. I have 5 ladies and I get 2-5 eggs a day, every day! They eat organic feed...but for extra protein, I give them some Greek yogurt on occasion...and they get meal worms every day as my way to call them back into the run. They just see or hear the bag and go nuts. Thoughts, anyone? I just think it is crazy that nature would have them lose their feathers in winter!
