Hi! Our 3 older chicks (about 7 weeks) are outside in their coop while our 3 younger chicks (about 5 weeks) are still inside. We have always had them separate, but close. We are getting ready to transition our younger ones outside. I've been letting them play in a enclosure outside where the bigger chicks free range for a few hours each day, slowly extending the time. So they can see each other, but not touch. Today I opened their enclosure for a few hours... their was lots of chasing, pecking, and all around bullying. The bigger chicks actually went into their enclosure and took over! lol. Eating their food and water and taking naps. Is this ok? Normal? Am I going about it the right way? Should I wait till they are all older, or is it best to get it done now? I'd like the younger chicks to start sleeping in the coop in about a week or so if all works out. Thanks for any advice.
