Here's my situation. On one side of the fence I have 11 hens and 5 roos about 9 months old. On the other side I have 22 17 week old pullets. They have been sharing the fenceline for about a month and I have seen no signs of agression from the older birds. Some of the younger ones are starting to get the red combs and wattles that indicate they are going to start laying soon, and I would like to get them to all be one flock. My concern is that the roos seem so much bigger than the pullets I am afraid they will be hurt when the roos try to be roos with them. How do I get them together without any of the pullets getting beat up by the roos? Once I have them together, I hope to let them free range when I'm around, but as of now they are kept within the pens all the time. The area is big enough that I don't have to let them range, but I would like to.
