Started this spring with 10 straight run chicks....and ended up with 7 roosters. We are "harvesting" the roosters, and so will be left with just 3 hens. We wanted a few more, plus I'm a little concerned they wont keep themselves warm this winter in the coop, since it is designed for 5-8 birds and is very open. Would love to get 2 more hens. See people selling them on kijiji but is this a terrible risk to take? Is there a way to minimize the risk of disease (as in, if you know what to look for)? The other option is to wait until next spring and get chicks again, though that seems like quite a wait... Any thoughts or advice? thanks!
