Automatic water cupsI had a whole bunch of used water cups/with pipes laying around and decided to make my own. This is a prototype but its been tested to work. The only reason it is a prototype is that I'm not sure on how many maximum of "add on Pipe" can be added. All you need to do is have a bucket cut a small hole smaller than 1/4 and hammer in the included connector. Then cauck it with waterproof cauck to make sure its water tight. I have used an earlier model already and the chickens love it. And started drinking out of it in 5 mins. It includes 2 water cups, 5 feet of tubeing and bucket connection. Extensions will be available soon. The water cups are used and pipe may have dirt specks on it but if you really really really want to clean it it can come off with some elbo greese. (I clean them to remove most dust only the really stuck on stuff remains but does not effect the water flow at all. there will be an extra 2 doller fee if you use paypal. If you pay by check it has to clear before sending it. Shipping depends on location.
