My girls are now 24 weeks old, and I've been getting between 12-16 eggs per day out of 25 hens. I have 5 ss, 5 slw, 5 bo, 6ee, and 5bo's. My roo is not doing any manly duties yet including crowing, and no my eggs aren't fertile yet either. 4 out of the 5 slw are picking at each other, and now starting on the others. They've only been doing this for about 3 weeks, and it started that they were only doing it to each other! 2 of the slw are almost bare, with an open bleeding area. I increased their protein level in their feed when I first noticed it about 3 weeks ago. The only other thing that is different is that we started keeping a light on at night for production. We've been leaving it on all night. None of the other breeds are doing it....any ideas to help....and what's the best thing to get them to heal up the fastest? Thanks so much!
