In a previous post I had written for help with chicken behavior. I had seperated 2 of my small flock the day after Christmas and put them in their own pen. The 3 others were in the original run this whole time. Once the aggresser was moved, the others stopped laying eggs. They had slowed down a while before, but then just suddenly stopped after this nasty bird was removed. The nasty one lays nearly everyday no matter what. Long story short, she is no longer with us. I gave her to a new home with lots of other chickens and roosters. Now, when I went to the other coop to clean and visit with the girls, the littlest one was in a nesting box so I let her be and when I came back later, she was doing the 'laying song'!! And there was an egg.....the nasty bird leaves the property and the other start laying the same day??? The nasty bird was removed from their pen for brutal behavior and they all stopped laying that day??? Coincidence? :/
