We are leaving on vacation friday and will be gone for 10 days. I've got someone coming to take care of my critters, but I was wondering about the water container I use. That is, the plastic ones with the red bottom. But I was thinking about a galvanized water container. Will it keep the water cooler longer? The plastic ones are useless in that aspect. I thought maybe if the galvanized one is better I would get one. I'm trying to make it where the water didn't have to be changed except for every other day instead of everyday. Now I don't have water access to the chicken house. You have to take them and fill them up at the tap. So any suggestions?
