Moulting seems to be a tramatic event in most poultry life cycles. I just read on BYC today on the feeding index, that increased protein is needed to handle the moulting and refeathering period. I also read that hens need protein to produce "protein" rich eggs. I started increasing the protein to my new hens last week and we have been getting more eggs. I don't know how this will work during...after a moult period. I just remember 25 years ago when we had chickens, the'd lay like crazy then start to moult and not ever lay again! Young and uneducated, I didn't know then, I hope I do now.
Best of luck to you!
