Hi, yesterday morning I noticed one of my Poland was acting unusual, I have 7 chickens 3 warrens 2 Sussex and 2 Poland's. I wormed them 2 weeks ago. All seemed very healthy doing there usual thing. Yesterday I went to let them out their coop, all where fine and came out straight away. I went out to get a few bits as we had a wedding to attend yesterday, we where running real late, so just before leaving at around 12 mid day I quickly checked there food and water, and eggs, one of my Poland's was laying on the coop floor, I stroked her to see if she was ok, she didn't move. She was laying unusual, wings slightly raised and body puffed up. I picked her up, and she was breathing, I tried giving her some water but she didn't take any, at this point we had 30 mins to get to the wedding, so I placed her in the nest box, and just had to hope for the best. We got home at 10pm and she had died hadn't moved from where we left her. Is this usual she is approx 18 months old. She had a messy behind which I was cleaning up but was told it would sort it's self out after a moult. Is there anything I should keep an eye out for with the others?
