I still have 13 days until my eggs hatch and who knows, they might be all boys and I won't have to worry... but when and how do I introduce the pullets. I have 5 hens and 1 rooster and am looking to add 2 or 3 to my flock if I can. Their hen house is used mostly for sleeping and laying eggs. It's not very big but they go out in the yard daily in general. Will my rooster try to mate with them? My roo is a little over eager with his mating cause he is young but I have one hen (they are all 9 months old I think) and she's never laid an egg and she does not allow him to mount her. She is at the bottom of the pecking order and she's the smallest and he still can't get on her (try as he might). Maybe I should make a little coop/chicken tractor first so the new ones can be in the yard where the others can see them and get used to them?
