This is Fluffy. She is around 20 weeks old and just started laying last week. Fluffy was fine yesterday, but this morning I found her like this. I am new to raising chickens and this is the first injury I've seen. I don't know what this is or what to do. How serious is this, and what can I do to help? Any advice would be very much appreciated. She shares a coop and run with 6 other pullets of the same age. I got 6 of them at 1-2 days after hatching, and one bantam cochin a month or so later. In my flock I have 1 buff orpington (pictured), 2 Americaunas, 1 Buff Rock, 1 bantam Cochin, 1 Partridge Rock, and 1 Maran. They all seem to get along fine.
