Hello, my name is Anni and I am the current chicken lady at Richland Student Farms in Decatur Illinois. There are a couple of us that will be on here periodically. I really liked the idea of having a school page so that anyone who helps with the chickens, and had questions or concerns, could pop on and chat! We have a flock of 30 RIR's and are just introducing our small chick mixed flock into the big girls run. So far so good! Taking it slow and keeping a close eye. Any advice on keeping the big guys happy while the little guys acclimate? Thank you!
and Welcome To BYC! That sounds like an interesting project, hope it works out well! It is generally best to wait until the little ones are the same general size as the older birds, a long period of seeing but not touching so they socialize and get the pecking order sort of started usually works well, either splitting the coop/run in half or having the little ones in a cage inside the coop with the bigger ones. Here is a really nice article on combining flocks that you might like
