Unless you have a rare/special breed, it's often hard to find homes for roosters. Many folks can't even have roosters, and for folks who can...well, when you only need one rooster for 8-10 hens and figure that half the chickens born will be roosters, you can see the problem...especially at this time of year, when everyone is trying to get rid of them (or find homes for them). Keep doing what you're doing, advertising on CL or any other place you can think of. I'd probably offer them for free, although many might want them for meat. It's a lot easier for folks who eat their unwanted roos - they simply process them.
