Hello! I went out to the coop this morning and found small blood splatters throughout the coop. I was in the coop last night at 7:00 and all was well - 3 eggs and 3 chickens this morning - all who were acting normal, and I picked each one up and inspected to see if I could find any injuries - nothing. There was a busted egg that had froze (-22 celsius last night) .. I'm wondering if perhaps the chickens injured a "pest" ? We have squirrels getting in throughout the winter and other rodents who make their way in at times.. Does anyone have any other ideas? Thanks so much!!!!
