I know they are supposed to lay white eggs but I'd swear one of mine is laying brown eggs. I did buy her from TSC (as an Isa Brown), so perhaps she is something else? Here is my rationale: 1) I have 10 hens (4 leghorns, 3 Isa Browns, 2 Australorpes, and 1 Buff Orpington) about 7 months old, and I have gotten 10 eggs on several days. I have never gotten more than 3 white eggs in one day. 2) I often see one "leghorn" (Pipsqueek) sitting on a nest, but when I collect eggs, the nest has a brown egg in it. Any thoughts? Is she really laying brown eggs? Is she really just barren not actually laying? Maybe she is some other kind of hen? Photos attached!
