After I rehome a few of my babies, I will have 1 bo, 2 ees and 1 white lehorn (7-8 weeks). The 1 cochin I have is likely a male so I am rehoming him. I've been offered 3 cochin chicks and 2 cochin/ameraucana mix chicks (not EE) that are less than a week old right now. I plan on puttin the older ones out in the coop tomorrow. If I brood the babies for 6 weeks, will it be ok to add them to the coop with the older ones? There will be a 7 week age difference.
