Hello all! First, thank you for tolerating another flock integration question! Here it is: I currently have 8 chickens- 1 Polish rooster and 7 just coming into laying hens. All are the same age, all raised together. Get along great. Have a ~30ft x 40ft pen and a coop they live in. I am buying them a new coop. Well, the one I found on Craigslist that I fell in love with... it comes with five ~2 year old laying hens. The new coop is 4ft x 8ft, with a run that is attached that appears to be about 3 times that size. We plan to give them an additional ~30ft x 20ft attached to the current area, when the new coop comes in. This allows for quite a bit of free ranging. This area is still even fenced separate from the current yard. Which might help with integration, I assume. I get the ideas of integrating- you put them next to each other and let them observe, correct? Will this make up of ages- the current chickens being younger- will that cause issues? Will having the rooster being younger be an issue? Also, for health/quarantine reasons, how long to keep them separated? In the end I want to get rid of the old coop, and have everyone live happily ever after in the new 4x8 with lots of yard space. I can keep the old coop up for a while, until everyone integrates. It has a tarp roof tho, so they need to integrate before fall/winter! (I have built the old one myself, haven't made the roof yet, and we decided it is just too rickety/ugly, lol) That was long, sorry! Thank you if you read to the end, I just wanted to be very thorough!!
