STILL having issues...
I have tried keeping them separate during the day to where they can see each other but not get close enough to fight, letting them free range together, letting them roost together at night, separating them at night...nothing is working.
I thought we were having an OK day today since they were free-ranging together for part of the day, but once they went inside the coop for the night, the aggressive hen did a 180 in about a second and turned on the other hen. I know most hens squabble over the roost, and they used to do that too for a couple seconds before settling down, but this was another attack. The poor little hen was trying to run out of the coop to get away...I am not sure WHAT else to try at this point. Am I doing more harm than good by separating them? I feel badly for them, they used to be completely bonded and this literally happened within the space of an afternoon. They have plenty of room, free range regularly, there is enough room in the sleeping box of their coop...they were both molting, but it seems to have slowed. I am at the end of my rope!
