I went to clean out today just like i do ever Friday. There was blood all the way along under the perches. There are 10 gurls in the pen some are 6 months some are 4 months and some are 3 months. They are all acting normal, it is just this blood i am concerned about. They are all, eating, drinking, following me and jumping up onto the food bin as normal. They were wormed 2ish weeks ago.
