Okay, a few weeks ago I posted my concerns about my small flock. For a bit of background, I have 1 bantam GLW, 1 Silky, and 1 RIR (who I rescued from another home where flock was being gotten by preditors). All was fine, and then my GLW hatched her first batch of eggs. Then, all hell broke loose. RIR was pecking GLW while she protect her babies in the nest box. After some of your suggestions, I removed the moma and the babies, put them in a large dog cage and housed them in the garage. It has been about 3 weeks now, and the garage is not smelling fresh in the least They had started getting cramped in there. Last week I tried moving the cage back into the coop, and watched to see the reactions of the other 2. Silky, fine. RIR, not so much. She immediatley stalked the cage until she was able to peck at one of the chicks through the bars. NOT GOOD!!!! So, we put them back in the garage until we figured something out. Do we get rid of such a good egg layer? I found someone willing to take her, but all the chickens they had have all perished from preditors. But, I didn't see any other options. I would not have her killing the babies. So, we have spent all day modifying the coop to house everyone happily. 8 x 8 foot coop, divided in half to house moma and babies on one side, and others on the other side. She now spends the majority of her time pacing back and forth along the divider wall trying to figure out a way to get to the other side. She is psychotic! Also, the RIR has become increasingly aggressive towards me over the past month or so. When I enter the coop to gather eggs, she runs at me, growling, and tries to peck at my feet. When I try to swat her away, she stands taller and tries to stand me down. I have become quite leary of her. Her eggs are not fertile and she is not even sitting on them anyway! I do not quite understand why a hen is so aggressive. I'd swear she acts like a rooster or something. What should I do to calm her down and make her chill. I have thought about getting at least one more RIR hen to keep with her or even putting a rooster with her to put her back in her place. Any thoughts as to why she is acting this way and what to do about it?
