Here's a neat story:
I answered a Craigslist ad for strawberry plants, and got an AMAZING price on established plants that will bear this summer. Yaay! The guy gave me such a deal, that I took him a dozen eggs, half of which were Marans eggs.
When I gave him the eggs, he said, "WOW, are these Marans eggs?" I said yes, and he said that his wife had been raising Cuckoo Marans for the last few years, but that her eggs were nowhere near that dark, and that she would love to have eggs like that. He asked if I would sell them some eggs, and I said, "Feel free to hatch those." So they are, and then I'm going to get some more to them in mid-April.
THEN, we got to talking about poultry in general, and when he found out I had Narragansett turkeys, he asked the amazing question, "Do you have any Toms for sale?" I nearly shrieked for joy.
Turns out his father has a flock of hens but lost his two Toms last year. So I quoted him a price for a pair of adult Toms.
When we arranged a pick-up time for the Toms, I jokingly said, "How about free roosters? ALL YOU CAN CARRY!" He answered that his dad would be happy to take up to SIX roosters, just because he likes having them around his garden, eating bugs, and to look at. So along with the turkeys, I packed up two White Rocks, two Cuckoo Marans, and two Black Copper Marans (the ones with the most excessive yellow on the hackles). Bye-bye, boys!
By the time he'd come and picked up the birds, we had also managed to make one more exchange--I had 10 pounds of organic Yukon Gold seed potatoes that I couldn't use, and he brought me 3 gallons of fresh raw cow's milk for cheesemaking from his parents' Guernseys! (This last bit was not a sale or trade, since that would be ILLEGAL in Arkansas, of course.)
