I've been selling a lot of what I hatch, locally. I have 5 ancona ducks on craigslist and a guy wants to buy some for his sister for her kids for Xmas, and has asked if he can buy them today and "store them here" till closer to Xmas. Is it unreasonalble for me to say YES, but ask for $2 extra per duck to help pay for feed & electricity between now and then? Afterall, they older they get, I bring prices up to account for exactly that. Money is tight right now in our house, and the extra feed without compensation is a pretty big deal.
