I want to make a DIY enclosed water bucket with water nipples to keep the water from getting mucky. I'm looking for advice on which is the best water nipple to buy? I was previously using a water bottle for rabbits, the one with a wee ball in the nipple, when my chicks were younger, but it just leaked everywhere emptying the whole bottle of water into the brooder so i was not impressed. I'm now using an upturned container in a dish, but they poo in it and get it all dirty and i don't like this method either. Is there a nipple for chickens that doesn't leak? I was looking at these ones on amazon but there is no reviews - http://www.amazon.co.uk/Cozyswan®-A...8428732&sr=8-3&keywords=chicken+water+nipples These are my first chickens so i'v no previous experience. But the nipples seem relatively cheap so i am prepared to pay a bit more to get the best quality ones that don't leak. Suggestions?
