I need input....My 6 hens are locked in a coop with a run in the shade during the day while I am at work. They have 2 containers of mash, 1 container of grit and oyster shell and a 1 Gal plastic waterer, filled with spring water. Temp yesterday was mabey 70. It's actually very comfortable in the coop when I come home to check for eggs. I refilled the water in the morning, and I make sure it's clean when I come home from work, usually it is..mabey a few shavings or food in it, but I always turn the waterer upside down and give it back fresh again. I wash it with soap and water every other day. I also heard they won't drink warm water and the temp of the water was nice and cool to the touch. So mabey 2 hours later I open the coop door to let them free range. They all shot up to the house where I have a glass bowl of spring water for them to use while out roaming, and they all horded it like they were so thirsty. The water in the coop was still clean, I just don't understand why they would do that. Does the plastic container make the water taste different? It's made for chickens. I just can't think of any other reason. What type of waterer do you all use.
