Thanks again for the suggestions! Today, I tried taking out my original boss, Gossie and putting the new chicken, Burnadette in with my other two easy-going girls, Gertie and Mya. It seemed to go well for a couple hours. Gertie and Mya put up no challenge to her, but it got to the point of Burnadette just going after them just because she could. So, I ended up putting everyone back where they were. Burnadette is alone tonight in the chicken tractor and the other three are in the coop. It almost seems like she is just a mean one, but she is the only one I have that is giving me an egg a day. Burnadette came from the country where she could free-range and now, she is in the city in a tractor. Maybe I need to find her a new home back out in the country? But it is really cool getting a fresh egg every day!
