So I had a thought. When I move my babies into the main coop with the adult birds, should I be concerned about the babies getting sick from the older birds? Im dividing part of the internal coop into a sub-coop to keep the youngsters in. Shavings and poo might pass between the enclosures. Should i be worried about this? Or should I have an actual dividing wall. I want the babies to be able to see the older birds so that when they are ready to be mixed we wont ahve an issue.
