I have 11 week old chicks that I need to introduce to my grown hens. We have an old dog kennel outside that we put them in during the day & the grown hens are free range during the day. But the grown hens has a coop they go into to go to bed. We have a area where we've barricaded to put the young chickens in the coop @ night. How do I start kinda blending them together?
