I have three hens(1 cochin(xl) 2 barred rocks), 2 chicks(1 barred rock/cochin, 1 cochin) that are in a seperate brooder from the coup, next to them in yard that will be 12 weeks when I have to move 10 (8weeks) other chicks(bantams crossed with black face and welsummers..etc) smaller birds outside. I was wondering do you think it would be easier and better to slowly introduce the 2-12 week olds to the 3 hens or the 10-8 weeks olds to the 2-12 week olds?
