I would suggest you increase price a good bit if you want to be taken seriously.
I know I like a bargain too, that's my name, bargain, for BYC!
But seriously our purchase ahead price for our Easter Eggers is $15 a dozen. Occasionally an auction for them will walk at a little over $12 a dozen. I sell eating eggs for $4 and up for chicken eggs - scrubbed and wash according to law and they won't hatch! Our duck eggs are $5 each. With some of our flocks, I have paid over $400 for a quad of NOT even full grown hens/roo. Many people on BYC have lots of dollars and efforts put into their flocks, to say nothing of the time and effort raising them, electricity of the brooder, time/costs making brooder and coop, and all that chick starter and chicken feed, water, etc.
Even our white leghorns go for more that that a dozen.
Now if you were nearby me and willing to work hard on my farm, i would exchange your labor for hatching eggs. I have done that with others. You might get a few takers but I would suspect many mutts or even worse, nothing would appear.
Please understand I'm not criticizing you but want to share the realities of costs and prices. I know you are presently learning the system so I thought I'd put my 2 cents in. Have a blessed day. Hope this was helpful. Nancy
