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.
Hens go broody when you don’t want them to… and won’t go broody when you do.
guess I'd better train myself to live in the now. :/ I've got my chickens finally and it's been delightful.
