5 Drinkers for sale in this lot - these hold 1.5 litres of water and allow the bird to drink from the red plastic bowl and it automatically refills from the white container.
They are relatively small so only suitable for only 1-2 chickens per drinker. If you have more chickens then you could look to buy larger water holders elsewhere or buy 2 or more of these and spread them around so that all chickens have a chance to go and drink whenever they wish to without other chickens being nearby and 'pecking' issues arising.
You fill the white container with water upside down, then put the red bottom on top and turn to lock, then turn the whole item over so the water then only comes out with gravity when the red bowl empties.
We used to keep 30 chickens a few years back and bought in a lot of these containers to use ourselves and to sell locally. Have had them in stored in the attic and they are in new, perfect condition, never used.
