So today I went out to feed my ducks and chicken and usually they all come run and eat (They have seperate pens). When I went into the chicken coop i noticed Snuggles, the hen, just laying there with her eyes closed, arching her back, so I figured she was just laying a egg or sleeping. About 10 minutes later I came back and she wasn't moving. I brought her some feed and water but she didn't even notice. I watched her for a while and a couple times she would just arch her back like she was trying to lay an egg but usually they lay after or before they are feed. Meanwhile, the whole time, she had her eyes closed. I decided to pick her up and noticed she was very stiff in her back area. Then what really worried me was she had diarreha that had some blood in it! I know diarreha could mean she has internal problems. I tired to give her water but her head just fell into the water and her eyes slightly opened and I quickly lifted her head but after a couple seconds her eyes closed again. I decided to check her heartbeat and it very very faint. I'm not sure what to do and I don't want another of my birds the die (Just the other day a fox killed one of my ducks and bite the other one but luckly he is fine)! Please help!!!
