Yeah, when I first started with buttons (about 2 years ago), they were from $8 a dozen and up....now I'm lucky to get $4 a dozen for them. But since you only have the one female, you might as well hatch the eggs and sell the babies, you wouldn't be able to send more than 5 or 6 eggs to anyone if you'd want to make sure they'd still be good. Or you could always feed them back to the buttons, that would eliminate the need for the cuttle bone
I'd take 6 or 7 eggs. I looked at the pics you posted a couple of days ago and they are cute! All i have is a tiny incubator that holds about 10 button quail eggs. All i have been seeing is like 100 eggs for sale. And i want only a couple quail. Just thought i'd say.
