I bought a dozen eggs from Wes today at the PSU farmers market. You can see a few blue eggs, these are from Araucana chickens, and I wonder if the few blue eggs at the co-op are from the same breed. He has 800 chickens he tends at his uncles farm. They are all kept in 7 mobile coops, ranging in size from 5 by 7 to 8 by 16. Instead of wheels they sit on skis, and are towed around with a tractor. He doesn't use fences, I was surprised at that. Apparently the chickens sometimes wander off and lay their eggs in the woods, sending Wes hunting for them.
