This morning, when I went to let the chickens out, I noticed the hens were behaving oddly - running from the run to coop. Went around and opened up the coop to find something very, very odd. Someone had laid a soft shell egg. The shell was crushed and to one side and the contents were off to another. That's not the weird part. The inside portion of the egg seemed to be full (and I mean really full) of blood. There was a pile of it to one side. On top of the nesting boxes, there was a big splash of egg-whitey blood (also from the egg, I assume). I didn't take any photos, as I had to wrestle the hens off it (evidently it was delicious). I cleaned it up and checked the girls over. All 5 of them laid yesterday and there are no signs as to who laid this one (the soft shell was grey, not brown or blue like the regular eggs are). The girls are all just under a year and have been laying for awhile. Everyone is acting fine. They were fed Countryside Organic Layer pellets, but I recently moved them over to Poulin Layer Pellets for cost reasons (a few weeks ago). They are offered oyster shell and grit on the side. I'm not worried about the soft egg (I know it happens sometimes). I am worried about the blood. It was a LOT of blood inside there. Should I be worried about this? If so, what could be the problem? This is my first flock, so any help or suggestions would be appreciated.
