i am trying to combine my 14 week olds with my my 22 week olds and am not having any luck, They have been in seperate coops but with ajoinning runs since the youngest came out of the brooder, but the first time I put them together in a large fenced area there was total mayhem. I decided to seperate them until they were closer in size. Today I tried adding one of the older girls to the young group and it went well except with one of the 14 week olds. As soon as the older bird pecked her she took off running and wedged her head in the corner. The other bird quickly followed and began pecking her on the back and she just layed there. I seperated them and put the older hen back with her group. I tried it later with a different older bird, with the same results. Does any one have any ideas on how to get these two groups together?
