i went out this afternoon to do the usual water change, treat time, collect eggs, etc.. i noticed one of the two chickens we have wasn't coming out of the coop to say hi so when i opened the door to check on her i noticed there was blood splattered everywhere. she was laying down looking exhausted, so i picked her up to see where it was coming from and noticed her behind. i cleaned her off a bit, took the picture, and came here. she was out and about yesterday and i didn't notice anything....how could this have happend so fast and what the heck is it and will she be ok? !
