I have a Plymouth Rock-beautiful chicken-suppose to be 1 yr. old. (My husband thinks she is older) I bought her from a lady that Co-op recommended. I have now had her for 6 months and never had an egg. The other two chickens we bought from her (Rhode Island Red and White Leghorn) are great layers. She thinks she is the queen of the coop bossing everyone around. I really love her a lot. She follows me everywhere I go when I am feeding or cleaning their coop. She loves to fly up and sit on my shoulder. (Not crazy about that but I let her for a moment). I also have 2 Americaunas that are 6 months old (not laying yet) and another white leghorn 6 months also, and started laying two weeks ago. They were babies when we bought them. My question is----How can I tell how old she is---and if she will ever lay? We feed with the Co-op feed for layers and also lots of veggies and fruit.. Does anyone have any suggestions?
