Quick question....been given 2 18 month old hens. Each laying one egg a day. Yes, I give a little cracked corn in the late evening and a little yougurt with tiny pieces of egg shell in it every other day. They are in the big chicken yard which still has lots of grass. They are not eating their layer ration that I can tell at all!! I have their feeding tray set just a little below their shoulder and it is full and clean. They seem happy, but I am worried that they are not eating! I do not know how the lady fed them before.....but I do know they were kept in a very small place with no yard.... So, ...is this normal, or are they starving?
