Hello! I have three hens... Mary, a Buff Brahma who just got over a respiratory illness (she was the only one displaying symptoms). She is about forty weeks old, and I don't think she has ever laid. I could be wrong though Then there is Cora, a RIR. She has laid almost every day since late October. She gives me normal looking, speckled brown eggs. Finally, Mabel, an EE, who just started producing white eggs last week. Anyways, I noticed Mabel (the EE) laid an egg this morning, and this afternoon I saw Cora (the RIR) in the nest box. When I collected the egg just now, I was shocked to find a very very very pale brown egg, almost white. It had a faint brown top, and a super thin shell. The yolk looked normal. This is highly unusual for her. She eats Nutrena Layer pellets with access to calcium free choice. Any ideas? She never displayed any respiratory symptoms or anything.
