Hi all...new to chicken keeping. My hens all seem well and laying almost everyday. This AM I discovered an egg with very soft shell on the roost. Looked like it was deflated and yolk was in the poop pan below. Everyone is eating well and have been making eggs regularly so should I be concerned? I only have 4 hens (2 Wynndottes and 2 Easter Eggers)...the Wynndottes are about 2 yrs old...we adopted them 2 months ago and they are settled in. I know it was one of their eggs because it was brown. Anyway everyone made eggs today 3 good ones and that oops on the roost. Ideas or thoughts?
