Well, like you've said, you live in an isolated, protected area where people still tend to adhere to the old ways of respect for life and community values ... and I truly, TRULY envy you for it! In more urban/suburban areas, like mine, it's a much more "throwaway world." It's sad, and truth be told, many modern-day, would-be farmers only respect the almighty dollar. If it's free or cheap, it's not worth much. Our local shelters are full of dogs and cats ... and people ... that the community has tossed aside.
Even if that weren't the case, though, I'd still charge extra for started pullets. My time and brooder space are worth something. The hatcheries charge $20-60 apiece for cross pullets, then add $49- 60 shipping, to boot. It's CRAZY!! Asking $15 apiece, delivered and already past the high-heat brooder stage seems quite fair, actually. And if not, I got them for home, anyway. I don't really need to sell them. The only reason I would is that I have another batch of Nankin eggs I'd like to set - and if I keep the Asians (yes, TSC egg production pullets,) I really shouldn't hatch more .... and I want more Nannies!
