My chickens are between 8 and 9 weeks old. They are EEs and Light Brahmas. Around 4 to 6 weeks or age (when I had my baby by emergency c-section) they were in too small of an area and did some feather plucking of the tail and shoulder area. I have been watching them very closely the last 2 to 3 weeks and I truly do not think that there is any more plucking. There are little feathers coming in on the shoulders. I can't tell on the tails since there is still so much fluff on the tails it hides any tiny feathers that might be there. Today when my son let them all out, his favorite chicken Blade, a Brahma, jumped down from the higher perch (maybe 3 feet up) and two longer feathers fell out. My son also found one longer feather from one of the EEs. Whats up?
