Yes, it can. Particularly if she is in the really, really bald or pincushion stage of molt. This is <I>another</I> reason to raise their daily protein level.can molting make a hen so uncomfortable that her appetite lessens?
When there are molting birds in my flock - and there ARE right now! - I give them a larger than normal amount of BOSS (Black Oil Sunflower Seed) for their daily hand-feeding treat. Every now and again, I will add dry cat food into their feed trough.
Chickens usually molt in late summer or fall. There are always the exceptions though. I had one molt in mid summer and one who hasn't even started yet. Chicks won't molt their seonal molt until they are around 15 to 18 months. But like I said there are always exceptions to that.
there are a great number of good articles and forums here on BYC as well as many good books out there. I read so many forums and books and magazines and still find so much new (to me) information! Anyway Welcome, again.
