I'm still recovering after my neighbors dog killed all 5 of my baby girls yesterday. I'm looking into getting new baby chicks. My farm store gets chicks every other week, and they're getting some that I'd like on 7/2, and some that I'd like on 7/16. Would I be able to introduce the babies to the two week old chicks, or is this going to cause problems, because the little ones will always be smaller? I do have the ability to split my brooder with a divider, it would just be so much easier to keep them all together. Thanks for the advice.
