Tonight I came home late and discovered my best two layers with bloody vents. I took one out and put her in a separate cage and put blue kote on her back end. The other one isn't as bad, but I used blue cote on her too. One of my BRs has a ring of skin instead of feathers on her neck. I blue koted that. Now, here are my questions: 1. They had been doing fine. The past few days, I ran out of feed and fed them scraps, feed bread, meat and vegetables. They still had some grain when it all was done, albeit not much. Did this cause the picking? 2. The rooster is getting pretty hard on the girls. I'm thinking maybe it's time for freezer camp. Could he have caused it? 3. What else might have caused this?
