I haven't had any chickens for about 15 years, so I could really use some advice. I currently have 7 chicks (6 weeks old) who have been residing happily in the outdoor coop for the last two weeks. Of the 7, it looks like I'm only keeping 3 (1 EE, 1 BR, 1 bantam cochin). The other 4 (2 EE, 2 bantam cochin) are almost certainly roos. I'm planning on keeping them all until they are 8 weeks just to make sure, lol. I also have 9 chicks (2 weeks old -- 6 SF, 1PR, 1NHR, 1 Polish) still in the brooder. I would like to move them out to the coop with the older chicks when they are 4 weeks old. So, my question is, in two weeks when I find my 8 week old cockerels new homes, would that be the ideal time to introduce the 9 younger chicks to the 3 older ones remaining? Since there are only 4 weeks age difference between them, I wasn't sure if I still need to do very slow introductions or not? Thoughts? Is 8 weeks a good age to send my roos to new homes? Thanks!!
