This is my first experience with chickens. I love my girls....7 Buff Orpingtons. They began molting last August and haven't stopped. They look terrible. I've checked for mites....no signs. They eat well but their laying has diminished to about one or two eggs a day. THEN last week one of the girls lost the colour in her comb and began to fail. We lost her two days later. Any advice ?? Thank you so much for all of your GREAT posts!!
