Whats everyones go to for water bowls for hatchling racks?
From what I have heard and seen, people commonly use deli cups.
I use the 4 oz Ramekin dishes. You can order them on Amazon or get them at Walmart. They are about 1.8 inches high and 3 inches wide. They are very stable and almost never get dumped and can be put in the dishwasher.
12oz deli cups.
I like using little ceramic ramekins and sauce bowls I usually pick up from Target. The weight keeps them from tipping, and since they are ceramic they are durable and hold up to dishwasher cleaning.
I use 8oz Ball Mason jars. You can use small disposable plastic cups w cut pvc tubes to prevent tipping.
