You've so very much to learn. I'd spend a whole lot more time reading, listening and learning in the "Learning Center", BackYard Chickens provides under the brown tab above.
The fact is that chickens have a strictly ordered society that is structured very differently than a human society or even any mammalian society. If you put a 5 week old chick into a pen of adult birds, the consequences are often life threatening to the chick. The birds see it as an intruder and many times? They'll peck it to death. Certainly, it will be chased, bullied and prevented from eating, drinking and finding rest. Integration is difficult. It can be done, but it appears you've not yet come to understand either the potential challenges nor the possible methods of successful integration.
Again, the BYC administration spent a lot of time writing the Learning Center material. Worth some time spent reading.
