I have had hens for a long time, yet I have never run into this problem as often. Years ago I had a hen that I found dead in the nest with her back end very open and blood all over that area. In the past 3-4 months I have had 6 hens found like this. Hemmoraghed and dead in the nest. 4 were mixed breed poulets and 2 were 2 yrs old comets. Have never seen so many cases of this, anyone have any info to share. Any advice would be appreciated.
