Hello all, I desperately need some advice. Sorry if this is kind of a long story but I want to paint an accurate picture. I have raised four chickens from chicks since April. All was well, they all got along, and we're happy and healthy. Unfortunately, mostly my error, but two were killed by coyotes. The other two seemed a little traumatized, but were okay. My vet suggested getting two more, as they feel more comfortable in larger flocks, so we adopted two more that were roughly the same age. I followed all the proper protocol of integrating them and all seemed well. They generally remained in two groups of two, but they weren't aggressive so I thought all was well. After about a month of coexisting I woke up to a dead chicken (one of the newbies) with all of her head feathers plucked off. Im so heart broken and feel like I can not do right by these chickens. The other newbie now only hangs out by herself and I'm afraid she will now get picked on or is just plain lonely. I could go back and adopt another chicken from her old flock, but I'm not sure if that's a good idea. Any advice would be appreciated!
