I don't think there isn't a problem with refusing to freeze or sell to someone who hasn't fixed the problem that got rid oftheir first groups. I have specific things I look for with some of the animals I sell. Now, if you were selling sexed male's, I would say that you should just let them go. I know my male's more than likely will be used for meat so I have to just understand that they will be eaten anyways and sell them as soon as I can since I won't be using them and they're costing me money otherwise
