I am sure someone will have what you are looking for, most of the hens I get off the farms to rehome are older. The one I just got I was told lays pale green eggs but beings she is 3 she may have slowed down. I have read conflicting posts on how much they do slow down and some claim theirs never do but it probably depends on a lot of variables (breed, care, etc) Right now everybody is just getting over molting so they haven't been laying like normal. I got my original 2 from Abby in Annapolis last Nov. She had a very nice selection. There is a buy/sell category here (you've probably seen that) but you may also want to keep an eye on Craigslist, the "Farm and Garden" and the Pet section.
