I woke this morning to find some bloody urine/stool in my chickens coop. Any suggestions? This is the first time having chickens. I have nine and would really not want to lose them. They are 6 RIR/Whiterock mix 6-7 weeks? and 3 Olive-Eggers about 5 weeks old. I am not sure who the culprit is ... they all seem to be acting happy and fine though. They were all in a little coop/run until last weekend when the huz finally finished the yard run and then they have been in yard run for a week. We made sure the area was clean, not treated and healthy. They have been foraging for bugs and seemed to be enjoying it. Any suggestions would be appreciated! Thanks!
