I had two Roos in with my 18 hens, but one of them (not Dr. Ruckus) was starting to get a little too brave with me, fighting with my alpha roo and my hens were starting to get bare on the back. We took care of the extra roo last Monday, I roasted him yesterday and made chicken salad and stock. I thought the hens might be off laying for a few days after we got everyone riled up catching him, but they laid 14 eggs the next day and at least a dozen a day since (up from 6-12 a day before).My sister had the same problem with her hens. She had too many roos and they were being too pushy with the hens. She moved all but 3 roos for 25 hens and now they are laying like crazy. So there is hope.
