I don't know what the heck is going on with a few of my girls. Two tan EE sisters in particular have been loosing feathers like mad, especially on and around their head. One started losing them about a week or two before the other one. I've checked them several times to see if I could find any mites/lice/whatever and haven't found anything. Opinions please! The poor tan EE lost about half a dozen feathers while we were taking photos. Diet wise, they eat layer pellets, with oyster shell and grit freely offered. Only recent change has been a flock block that I offered about a month ago when the yard was covered with snow. They free range the yard during the day. This is a pic of what the hen looked like when she was young and had all her feathers. Now she is the pathetic one on the left. This shows all of the pin feathers on the back of her neck. Head and front of neck are all bare. There are little black dots (old blood?) where the feathers used to be in a few places. Pile of feathers collecting in the corner of the run. These two girls are fine except that on the front of their neck they are both missing feathers. It is something new in the past week. I don't know if they are doing it, or another hen is picking on them. The Barnevelder lost her tail feathers due to a dog and just hasn't grown them back yet. Blurred front view.
