No worries..the chicks can transition very quickly from nipples to open waterers and back again. They learn quick and well when little, but not so easy to train older birds to the nipples if they have never used them.
I've got my current nipple bucket hanging right next to the heat lamp in my chick brooder...can't really get any water on the lamp when it's contained in a bucket, so no worries that either.
After finding out about these nipples I'll never raise chicks any other way...it's just so nice having clean, large volumes of water, dry bedding, etc. instead of tipped over waterers, dirty water, wet bedding, etc. that one constantly has to worry about or clean up. Wished I had known about them years ago!
Okay, I'll definitely look into getting a couple! I have a bunch of fruit jelly buckets from one of my local donut shops that I had intended to use for FF, but it didn't work out. They seems to be about the right size and will likely hold plenty of water.
I normally don't have much wet bedding to worry about because I put my buckets up on bricks so nothing spills, but maybe less water will be wasted when these birdies have to reach and up take a drink instead. Those ducklings are so funny when they drink, though. They try and put their chests right into the water and enjoy the feeling before realizing that the quail are poking them to get out of the way, hehe!
