We have one Narragansett hen, one BR hen, and two Rio Grande Wild hens; all hatched mid-May, though I think the Narragansett may be about a week older than the others. They've been fine all along, but today all of a sudden the Narragansett started fighting with the BRs. At first I think she was fighting with the BR hen, but by the time we got in there to break it up, it was her and the BR tom, grabbing each other by the throat-wattles, really going at it. My wife broke them up and got severley pecked for it. Then all three birds started doing the tom display - wings down, tail out, feathers fluffed, the whole deal, even though two of them are hens!
We separated them and put the Narragansett in with the chickens, which are in the adjacent run, just a deer fence between them. They kept up the fight through the fence for a while, then finally broke it off and the Narr spent the rest of the day moping around and occasionally pecking a chicken.
I tried putting her back in late in the day but she went right after the tom again and he grabbed her by the throat... so back into the chicken yard she went.
We were gone over the weekend so they may have started this a day or so ago. Last night when we got back the Narr was roosting in a different place than before, so we wondered what was up.
So is this a hormonal change that will pass quickly, so they can be put back together, or do I need to keep these birds separated for a while? It seems like they can do real damage, so I'm reluctant to just let them work it out.
