I was preparing eggs today (eggs were not today's but within the past few days) and when I opened one it was totally bloody. Not little spots of blood - so much that I wouldn't eat the others which were already in the bowl becase the amount of blood discolored the entire bowl. This evening when I went to the coop to make certain the girls had all gone to bed, I found bloody poo below one of the roosts. In the morning I'll inspect butts to see if I can tell who it is. Any other suggestions?
