omlet glug any expierience ???

hello again no more moaning about the cube I promise but does anyone have any experience at getting hens who are used to a conventional drinker to use the glug??? I'm not bothered really they can keep using the old one if they want but the don't seem to know what the glug is for

But will they use the teats? Mine don't never have and I imagine never will

I have recently acquired some quail and had read that you could use a waterer suitable for rabbits - the ones with the ball bearing so that the user has to push this out of the way to obtain water. I got one but was very dubious about their ability to work it out but they did and very quickly.
