Hi I was thinking that's how I would integrate them. In fact I started already by allowing one hen out with the chicks and seeing how she would act towards them and then I let another hen out. They went up to a couple of the chicks and stared at them and the chicks did the same and then the hens tried to peck a couple chicks but the chicks didn't run away they stood their ground and then they walked away. Tomorrow I will let a couple more hens out until they are all out together. I'm definitely going to be right there to make sure no serious fighting happens. I'm going to keep them separate at night.
