last weekend we moved our 36 chicks from the large box in the garage to their 8x8 coop. yesterday i found 1 chick who was pecked hard removing most of her back feathers and flesh of a wing. i removed her and put her in a cage by herself with feed, water and antibiotics in her drinking water (tetra-something). everything looked fine when i opened the coop this a.m. - within the last hour i've found two other chicks aggressively pecked with feathers removed and bleeding flesh. all the same breed (jersey giants) have been injured; the tetra tints (TSC hybrid) are fine. what's happening!!! what can i/should i do? please don't leave me hanging here . . .
