Hello! I'm looking for some advice on replacing my 2.5 year old, infertile rooster. He is aggressive toward one of my hens so that is also a factor in his dismissal. I have 8 older hens (anywhere from 1.5 to 5 or 6) and will be adding 3 young pullets in a month or two (as a trade for chicken babysitting). A friend has given me an extra 13 week old rooster and I would like to know how to phase him in? I would have liked to add the pullets and rooster all at once as it's been a while since I've added any new members to the flock, but it just didn't work out. Any advice is welcome! Thanks!
