Hello all, I am a newbie and my oldest chickens are about five months old. There are three of them, I’m assuming they are pullets because I haven’t heard any crowing or seen any real aggressive behavior from any of them. They are pretty docile in general and very friendly (beggars) towards people. I have five more chicks, 3 are six weeks old today and the other two are four weeks old. I’ve been taking the babies outside in a small coop (that was originally intended for my bearded dragon, sorry Liz) while the older three are free ranging and they have exhibited curiosity but no aggression towards the younger ones. They also used to roost on top of their brooder and investigate. However yesterday I decided to let two of the older three mingle in a free range setting in my yard and two of the original chickens chased and pecked. Not -terribly- so but still. How should I continue to go about this? Should I let the older three go out with them during a supervised free range til they get used to each other? The four weeks old are tiny compared to the six, one being a naked neck, and I’d really feel uncomfortable letting those little things out with the “bigguns”. Advice is well appreciated! Also my run is 16x14 and the coop itself is a shed that is quite large and at least 14 feet on one side, probably about the same square.
