my two year old BO is losing her feathers. She gets alot of them plucked from my little feather addict Scarlet, another BO. But today she shook herself and many feathers came out. Just today I noticed her missing chest/neck feathers. she looks like she is in a molt. new feather shafts are coming out,I went to pick her up and snapped off three tail feathers! I see no bugs, she is eating and roaming with the flock but has seemed a little sluggish this pass week. I have been giving her/all some electrolyte solution, BOSS, 18% layer pellets, veggie snacks and ACV in their water twice a week for the last three weeks. pop looks fine, not sure if she has layed, she is a good layer, but abdomen does not feel bloated. I have a sig. feather plucking problem going on with three of my hens. any suggestions, I am planning on dusting her since I have never done it and all my methods are failing
