Okay if you have a hatchery or something that makes a business yes ofcourse you do. What I mean is.... Your hen has chicks of her own for the first time! Yay! But you can't keep them all, uh oh. You have a flock of 28 already and you don't have room or can't afford anymore. Hmm, hey I know, how about a casual sale? Just like selling puppies or baby goldfish. It won't happen all the time so you don't need a license, right? Well my dad says that you do and if it's a casual sale I don't see the difference from selling one time chicks to one time baby goldfish. Well maybe not chicks, more like pullets and cockerells. I want my nice mutt to have babies with either the barred rock, cochin, or new hampshire. I don't like breeding purebreds all that much, I like different things. So do we need to aquire a business license just for selling a batch of pullets/cockerells for one time? Probably only like twice a year I'll let a random girl have her own, maybe only once.
