Yesterday I tried to put my 3 1/2 month old girls in with my established hens at sunset. There was a lot of pecking going on and when I watched them this morning, again, there was a lot of pecking. My poor babes were all hiding in the corners to get away. My 9 year old went in the run and picked up one of the peckers and poked her a few times and said"now you know how it feels". We finally took them out. The babies free range with the hens on a daily basis. Should I wait until they are closer to laying age and try again? Should I let this pecking go on as long as no one gets seriously hurt? Should I try again and stop worrying so much?
