What is the right age to put young pullets/roos in with the older hens? I have 20 older chicks in a hoop tractor. They are really starting to out grow it. I got them first of March from Rural King. So they are about 6 weeks old. If you can believe it, I have two that still have fuzzy/fluffy feathers and aren't fully feather yet. They seem to be the same breed, same color etc. I plan on keeping any pullets. The roos (all except one or two) are going to be butchered when a bit bigger. If I could take at least the pullets out and put them with the hens, it would free up some space. I just don't want the hens to tear them up. Thoughts?
