Agree with that.Note @micstrachan on a really hot day, I wouldn't risk removing all water, as it is critical they stay hydrated in this heat........I should have put that caveat in my previous post....shame on me.
I didn’t take away water just because it wasn’t mission critical that they learn as I was going to keep the other waterers.
As it happened though my chickens have a great FOMO and so when one was tapping away the others wanted to see what all the fuss was about!
Interestingly some of them have different techniques. Diana is a master nipple user and never misses a drop. Maggie on the other hand attacks that nipple like it is a meal worm and as a result only actually gets water on half her ‘stabs’. But she loves that thing and will be banging away at it even when there is other water right near by!
