I have 2 hens that will be 2 years old next month and 5 hens that will be 1 year next month. When they are out of the pens, they for the most part are fine together. My "Firecracker" even after losing all her feathers is still the "mean girl" and goes after all of them from time to time. I want to put the 2 older ones in with the 5 younger ones so I can get ready for a new batch. Any suggestions on how the best way would be to do this. Tomorrow I was planning to try to place them in with the others for an hour or so to see what happens. Is this a good idea???
