Unfortunately, you will not know if they will go to "good homes". You can post any kind of ad you want, you can charge for them so people won't be getting a free meal, and you still won't know once they leave your place. The thing about charging a price for them, is, if it's too high, you're not going to be able to find a buyer in the first place unless they're some rare or special breed in high demand. If you charge a lower price - even as much as $5, that's a pretty cheap pot of soup. If you want them to continue to have their good, loving home, your best bet is to build a bachelor coop and keep them that way. Or process them yourself. Think of it this way - by processing them yourself, you will be rest assured that they had a very good life, up until one bad day. And they won't even know what happened on that day. If you use the ax and stump method, they will know that for some reason you grabbed them, and then it will be over in seconds. It would be harder on you than on them.
