Hello, I have 6 hens and 5 are kept separate from the other one. In the group of 5 one is dominate and was plucking feathers. I am doing the WI project (salt water every 3 days) and letting them free range again after a bobcat attack. I lost one of my rooster chicks. So 4 of them have plucked feathers on their rear ends. The plucking started when the free ranging stopped. The 5 hens have a running pen 12' X 15' with a creosote bush, 3 laying crates, roost ladder. I have been using Blue Coat when their skin is red and irrated looking. When its not I use Monkey Butt powder with corn starch. This morning I noticed one lost all its tail feathers on the roost last nite. When coating with Monkey Butt another one tried flyng out of my wifes grip and lost some feathers (fell out). Rear end area. I am under the impression they are molting. The feathers that fell out are light and fluffly looking. Egg production really slowed down from up to 5 eggs daily to 1 today. They are 10-11 months old, weight is good and well fed. Layer feed, scratch, black oil sunflower seeds, coral calcium, egg shell, veggie & fruit scraps. Is it normal to molt in January? Todays date is 01-05-13. Temprature was 27* last night. Thanks.
