When I went out to open the chicken coop this am I found my pretty little Emma dead on the floor. Yesterday she seemed fine, and the rest of the girls seem ok. I couldn't see any marks or anything. She was about 3 months old, and very small. The other chicken are different breeds 2 Buff Orps, two Partridge rocks, and a gold lace wyadotte. They were the same age, but twice as large as Emma. Now I'm afraid it is something catching & something will happen to the others.
