A few weeks ago my EE shocked me when I saw she was missing her entire muff, all the way around. I have treated with sevin in case it was mites or lice. I have checked regularly and retreated even though I have seen no bugs at all. During this last few weeks I have seen that my other EE is looking scruffy and missing some feathers on her wings. A few feathers look like they have been stripped of fluff. Those are also on the wings. My BO has some feathers that look like they have been trimmed at the shaft about 1/2 inch from the end making an odd V shape. This is toward her rump and could be from my BA. NOW today I noticed that my Hamburg is missing neck and head feathers as is my GLW. I clean the poop boards every day. I put DE on the boards and a little sevin on the roosts when I clean. Fresh water every day and food available 24/7. Egg laying is near normal for them with only a brief slow of 3 days this week only getting 4-5 eggs when the normal is 7-8. Activity and appetite seems normal for all of the birds. Food has been changed to all flock on Sunday since I had noticed my BA eating a feather she stole off the BO. Combs and wattles are all red and healthy looking. Weights feel about normal for them. Legs look good.... well as good as chicken legs can lol. Could this be a partial molt at the wrong time of the year? Treats are as follows For 10 hens: On Sunday Oatmeal with craisins in it about 3 cups total Monday, Tuesday, Thursday, & Friday Scratch about 1 and 1/2 cup Wednesday and Saturday is one of the following Leftovers of cooked corn, broccoli, steamed rice, peas, cheerios, apples, or banana Any thoughts on what in the world I am dealing with?
