I am new to chickens and just starting with layers. We will be raising up and butchering the extra roos. We have the chickens for various reasons, one being self sufficiency. I would like to raise meat birds, but from everything I've read, I need cornish x to really be worth my while and they don't live for breeding. So if I'd like to be able to breed my own birds for meat, would I be better off dealing with the less cost efficient roos of my dual purpose breeds? Is there a good breeding pair you'd recommend for meat birds that will live healthy enough to breed out? Do they tend to be more aggressive and would they need to be housed apart from my regular laying flock? I'm having a hard time searching for this info. I do not want to simply buy x's every year because it's more cost efficient, but I also don't want to waste a ton of money.
