I got 3 hens a year ago for Christmas. I was told they were 6-8 month old production hens but one (the one in question) looks more like a Rhode Island Red. Her name is Marcia. (The other two are Jan and Cindy). Well Marcia started laying in February and laid 33 eggs in 5 1/2 weeks (only missed 3 days in that time). They were beautiful dark brown eggs. And she hasn’t laid an egg since. Other than this she seems perfectly fine and healthy. She does encourage the others, often she is in the nest with them! But she has yet to lay another egg. Do y’all think she ever will? The only other difference is she seems a bit aloof. She’ll be the last one to come when they come for treats, or slowly walking into the run when they go in. In her own world but probably just her personality.
