I have a roo that is over a year old now...he has been with another roo this whole time. They can see the girls that free range and talk to them through the fence and a couple of the girls seem to really like him. I am making a breeding pen because I need to hatch eggs from him now. Who do I put in the pen first? I know the girls will probably be upset because they have always free ranged. I can't let him out because my free range roo and he always fight through the fence(or try). What is the best way to go about this?
