When I got home today I went out to the garage to fill the water and food dishes for my 3 chickens. I noticed blood all over them. I examined my girls and one had dried blood all over her comb. I don't see any cuts or anything that stands out. I looked around the garage and didn't see anything either but I'm sure there's things she could have cut herself on. I thought maybe it just got really cold last night but I'm still not sure. The reason they are in the garage is because the coop they were in isn't suitable for winter and the garage is WAY warmer. We are in the process of moving so their new winter coop is at the new house. Any ideas?
