Is there anyone in the Phoenix, AZ area that I could contact? We have lost all of our original hens who would have turned 3 in May. I know the heat is hard on chickens, but I really would like to talk to someone. Our last hen of the group died Sunday, after it got hot last week. We only had two from our original group because 5 of them ended up being roosters, but we purchased two others a few months later and all 4 have died. I have 3 others and hope to try and keep them around longer. They all stop laying at 2 years of age. A month or so before the hens die, always when it is hot, they have diarrhea. I have done testing for parasites/worms. Maybe they just have runny poop due to drinking more water because of the heat. I'm just curious if there is something I could be doing differently. The other chickens never get sick, so it doesn't seem to be contagious. They have a large open coop with a run and an area where they can free range.I couldn't bring myself to do a necropsy,
