We have two 3 week old chicks from our first hatch and the second group started hatching yesterday (16 out so far). I have a big brooder cage that the original two were in by themselves and wanted to have the babies in there too. Not that easy I guess. The 3 week old try to peck the little ones (who are brave little things that peck back!) so I put them in a large cat carrier next to the brooder (temporarily I hope). Any tips for helping the two groups to get along? I was thinking of doing a few minutes of supervised play time together each day for a few days so they can get acclimated to each other. Would that work?
