OK I have two nice sized bantam Polish Roosters and 9 hens. 2 hens are bantam Polish, 5 are standard Polish and two are large sex links. Why are my two Roosters only wanting to mate with my little bantam Polish hen? How can I get them to try with the other hens? Some are almost the same size as them so they should be able to but they only want to mate with my tiniest hen? And another question: My other bantam hen acts scared so the Roos can't get close enough to her to even try mounting her. If she sees them she takes off running? They are all in a large room in my barn. Should I place them in a small pen so the girls can't run away? And if so how small of a pen and how many should I put in with one Roo. Thanks for your advice...
