I get my chicks this Thursday so I'm still quite awhile from drinking water in the coop/run but I'm always thinking about the next step because this is my first go 'round with chickens. I have horizontal nipples that I was originally going to use with a PVC pipe system. I was talking to another chicken keeper this weekend and he said that he tried that method also but the inside of the pipe would get all gross with slime and whatever and said it was just huge pain to clean out. Q1- Has anyone here experienced this and how do you remedy it? This person also said that they now use the bucket system with the red/yellow cup system and hangs it from the bottom of the elevated coop and they love the simplicity of just having to clean the bucket. I would tend to agree with that. Q2- What is a good height for the nipples to be at? I'm sure it varies for different types of birds and ages so let's just use some general guidelines. Thanks so much!
