Friends, I just went out to lock up my lady loves for the night and ones of my gold sex-links was dead in the run! I was out there around 3:15, so it has been later this afternoon. Her comb is very slightly bloodied, and she has blood coming from one of her nostrils. I don't know if the comb and the blood in her nose is related -- my sex-links and BRs quibble over food, so an occasional bloody comb isn't unheard of for them. They have always been on the more aggressive side toward each other... I'm totally baffled! No one has been acting sick at all. I recently reseeded part of my lawn, and as you know all grass seed is covered in chemicals. My coop door is weird, and blew open in some wind on Saturday. I wondered if she ate some of the seed? But if she had, wouldn't it affect her sooner? I'm so worried now guys!! I didn't love my sex-links. They are stinkers, and are super aggressive to my other breeds, but I hope she didn't suffer. I hate thinking of animals suffering. And are there any diseases that would make a chicken bleed from her nose, and then die? There are no signs of foul play. We have recently attraced some rats.I haven't ever been around rats, but I don't believe a rat could kill a healthy, and persnickity hen. Right? Thoughts?
