I'll chime in with what I've read on other posts; I'll be going through integration soon too.
Since I don't free range, I don't have much to say about it.
Too much is a bird holding down another bird and pecking it. Too much is the fight going on long enough to cause injury or draw blood. Too much is several against one. Too much is not letting the little one go when she runs away, and chasing it non-stop. (Be sure that there are "out of sight" places for the littles to hide behind or get under. Be SURE it's not a dead end. A pallet leaned against the fence is what I've seen recommended.)#4 - Realizing that there may be some harassing/pecking/chasing going on during integration. I understand that I shouldn't intervene as it will disrupt the process. But, how much is too much? When do I step in?
I'll be mixing them together until the starter feed runs out when the littles join the adults. Just be sure to have oyster shell (or crushed egg shells) and grit available for whomever needs them.#3 - I really have no way to separate the 'baby chick feed' from the 'laying hen feed'. Therefore, is it OK to feed the new chicks the same laying feed as the older ones? Is it really that much of a big deal? (Again, the new chicks are 9-weeks old).
