Hello. I am ready to enter my 2nd rooster into the flock. I was wondering whats going to happen before I do this. I mean Im going to have the one rooster in a cage for a few days to reduce fights. I have 12 sexually mature girls. And I have around 16-18 pullets at 6-7 weeks. I know I dont have enough girls that are mature but I will in 10 weeks or so. But will the rooster pick and choose their girls? My coops ok sized. and when Im home they free range.
