I know it is said that roos are not needed to get eggs from hens but I have witness something different. I have roos and my gals are always laying, brooding and raising chicks, year around. I have a few "delicate" hens, some of them older, on my porch that I keep away from the rest of the flock. They are protected from any bullying and over mating by roos. I have a young roo that I hand rasied who comes up on the porch every once in awhile. One of my hens who stopped laying for now just restarted laying. I think it is due to the young roo's interest in her. She doesnt like him to jump her but sometimes it does happen. I notice that when I am diligent keeping him off the porch she stops laying, for weeks. Then when he gets up to have access to her she starts laying again and will continue to lay an egg per day as long as he comes to visit regularly. Do you think there is anything to my suspicion that roos do indeed influence the laying behavior of hens?
