I have two batches of chicks that are 13 days apart in age. Six of the chicks are 24 days old and 15 chicks that are 11 days old. They are currently in the same brooder with a wire partition seperating them. [/img] (picture taken prior to hatch) I am wanting to remove the divider at some point. Would it be okay to combine them now, or should I wait a little longer before merging?
