This is my first year raising chic kens, and, besides a freak power outage where we lost one chick, we have been able to successfully raise 6 hena, and, one unexpected rooster!! Tonight, my dog chased a couple hens, while I was in the backyard. I thought I had stopped her in time, but, about 15 minutes later I noticed a hen huddled in the run. Now, I hadn't really paid attention to all of the hens at this point, so, she may have been there prior to the dog incident. When I had come outside, the rooster had flown out of the run (there is only a small area that we haven't covered yet, and, he has NEVER flown very far, so, I was trying to get him to go bak into the run. Anyways, she is VERY lethargic, she CAN hold her head up, but, just doesn't???? I really don't think she will make it through the night, but, if that is the case, how do I determine if I need to protect the rest of the flock?? Should I, if she does pass, do a full scale disinfecting and scrubbing of the coop, and, run??? I went into this knowing that I would lose SOME of my girls, BUT, it's still hard, and, of course, I don't want to lose any more!!!
