I have never had any luck with Craigslist, even tried listing them for free. LOL seriously, I end up giving them to my local feed store.
The family I loaned my incubator to was asking about unwanted roosters for meat birds. She lives in Modesto & her daughter has a poultry project going for 4H. You may have met her at the lunch table at Stockton.
She's welcome to them.
