I'm happy to say that I found a farmer who is willing to sell us some 26-ish week old chickens who are good egg producers for the low-low price of ten bucks each.
I explained the challenge, and asked him if I can wait until the spring when we've fenced in the yard, and he said yes :o)
Woo-hoo! I'll have eggs to trade! (As long as Mark doesn't come eat my chickens.) (Mark, they're still off-limits. No hunting in my yard.)
