I want bigger birds because we like sending most of our young roosters to freezer camp. That is why I want to phase out my Leghorn mixes, they are lacking in meat, that and they are flighty, hard to handle and master escape artist.
How big are the chocolates you have? If they are broody I might be interested in some come spring, even if they are smaller. How hard would it be to get new blood for the breeding line?
To hens get broodier as they get older? So far, I had one Dominique and one Dom/Buff go broody this spring and one Buff go broody about a month ago. I refuse to let the Dom hatch eggs though. She is vicious when broody, plus she kept playing musical nests. My Dom/Buff and Buff make a lot of noise and they fluff up like puffer fish, but they've never offered to bite me, let me handle them and the eggs, and are really good setters.
