So, it turns out BOTH of my brahma's are boys! I got them from a feed store as 3 day old chicks with a 90% chance of being female. I have no idea how those odds can be correct. Anyway, yesterday my husband fashioned a home for them away from the girls. We are hoping they will live happily with each other there. So far, they have not been fighting with each other. I'm not sure if I'm doing the right thing though because one of my girls in particular seemed very upset with me for taking her men away. I just really don't want either of them to rough up the girls since there's only three in my flock and one of them is a bantam. Any thoughts?
Addressing the ratio issue: two roosters to three hens might be an issue. I wouldn't worry so much about one hen being a bantam, though. It does put more pressure on them.
What I would do first is wait and see how the personalities develop. You might want to move one of the roosters out of the new coop and move the hen who was upset into the new coop with her man.
If that doesn't work out, try getting a few more hens, and or removing one or both of the roosters.
