Hello,
If they still need homes I am willing to take some in if you are willing to ship them? I do not know how shipping works, but I could even send you some money for the costs (after I receive the birds). I also have RIR and leghorns and I do not mind that they are past peak egg production since most o mine are as well. As long as they still lay occasionally I'll take them (some of them). I do free range all of my chickens, and I give them a few too many treats, so they would have a good home. The most I could honestly take would be around 10-15, as I may have a large yard, but the coop they go into for night doesn't have much room left and needs to be upgraded if I add more birds.
But I don't like the sound of all 750 being culled just or the heck of it.
I actually got my chickens originally because they were going to be killed and wasted if no one took them.
I live in North Carolina, so it is a little far, and like I said already, I don't really know how shipping them works and if it is even safe or reasonable for the distance.
I have RIR hens, and White Leghorn hens, and I could even take a leghorn rooster. But I have a red roo so don't need any of those.
