Went outside today to check for eggs about an hour before dark. I noticed one of our White Leghorns laying in the nesting box. When I turned it around I noticed she was dead. She had laid an egg yesterday in fact our three WL usually lay almost every day. She had shown no signs of being sick, ill, tired or anything else that I can think of that might lead you in a certain direction. I do know we only got two white eggs today from them (our only white egg layers). She was 8 months old, she died in the nesting box with what appeared to be a slimy liquid coming from her vent with something that kind of looks like cooked egg whites but very fine in consistency. Anyone have any ideas what might have been the cause of her death? Everyone seems to be doing fine and our entire flock free ranges on our fenced in one acre back yard. It has reached 30 degrees here this week, but they all were excited and moving fine when I let them out at 7:30 am this morning.
