I know and I have been doing a lot of reading, but seeing as how I already have a mixed flock I don't see how one/one more rooster could do anything. Also is there something about mixed breeds I should know? or do you just not like them? Also would it be ok to have two roosters with 6 hens? I know most people don't like less then 8 hens if you want two roosters but I'm just checking. Worst thing is I either don't take a rooster or give a rooster to someone else.
There may come a time unbeknownst to you that you may have to re-home some or all of your flock for some reason and re-homing purebreds is going to be much easier than re-homing mixed breeds. Mixed breeds often just become someone's dinner -- unless that doesn't matter to you.
