Hi everyone! I just started with chickens this spring, with 8 straight run chicks. They are now 10.5 weeks old, and I have ended up with 4 roosters (one BCM, one GLW, two splash Ameraucanas) that I now have to get rid of somehow. 
I would like to add a few more girls to my flock to make up for the roosters, and I'm wondering which is the best way to do it. I was thinking it would be best to add some pullets around the same age; I have found a few available at local farms, ranging in age from 5 weeks to a few months. The downside of that route is having to quarantine. The other route is sexed chicks - but is it a problem that they will be a lot smaller than the existing birds when it is time for them to move out to the coop? What would you do?
