With all these chicks running around, and half a dozen day old turkeys ready for collection tomorrow, I needed some more drinkers. Luckily our neighbour showed me a neat little design that he has been using for years:
All it is, is an empty lemonade bottle with the base glued into an old plant-saucer. There is then a 6mm hole drilled right near the base of the bottle (for reference, the water level will come up to just above the top of the hole). As you can see, the bottle does compress a little as it empties, so use the thickest you can find. However, this doesn’t affect the function at all.
Nice and simple!!
