My neighbors pay us to keep their chickens in our barn. I was letting my ducks outside to free-range one afternoon, and I walked by the area where my neighbors keep their chickens. Since it's been humid lately and around 90 degrees, it was really stuffy in that area of the barn. The chickens were being really loud, and squawking more than usual, like they wanted something. I looked into the coop (more like a pen rather than a coop), and I counted 6 out of 7 chickens. I walked inside to make sure that all of them were there, and saw one of them sitting in the corner, wings slightly spread, panting, with her eyes slightly closed. I started to panic, as my neighbors weren't home at the time, and went over to pick the hen up and see if I could find what was wrong. she was limp, and let me pick her up. this was a little weird, since she was the kind of chicken that would peck your fingers off if you touched her. I instantly thought of heat exhaustion, and blamed myself for not running a fan inside that area. I went over to the waterer, thinking I would dip her beak in to drink, but it was COMPLETELY DRY. BONE DRY. I knew there was no way that they had drinken all that water. the waterer was HUGE (I would say 5 gallons). I also have 7 chickens, and they don't even finish a 5 gallon water in an entire day. It was only about 1:00pm, and the heat was HORRIBLE (80% humidity, 96 degrees F). These chickens clearly hadn't had water for the night prior, let alone today. I filled their waterer, and they drank for about 10 minutes straight. I started running a fan, and offered the sick hen some ice water, and she started to perk up. This wasn't the only case of neglect, there have been several occasions when the chicken's had no water, sometimes even no food. they haven't been outside in 3 weeks, and the door to their pen is sometimes carelessly latched, allowing them to escape at night when coyotes are out. What do I do? I don't want them to lose a hen due to their carelessness and neglect.
