I know it's tiny, but this is literally the only sign of anything. My husband found it when he was snipping around the edges. It has a reddish tint to it, but I'm not sure if you will be able to tell or not.
And I am more than happy to tell you all I have 6 new girls that we are bound and determined to keep safe! My husband built a whole 2nd story to the existing coop and has more than reinforced everything. They are still inside right now but we should move them out in the next week or two. I'm still a little hesitant but will have some faith! Thanks again for all the support. I will post pics of the new girls soon!
