Here is my zero waste feed and water setup. Just like Kathleen's my chicks could fit in the holes when I first brought them home. Added some doubled over duct tape as a temp boarder and we were good to go! No gravity feeder element just full so the can eat and since its so big (holes around 75% of the coffee container) we will only have to top off twice a week till they grow more.
Wow! I like the coffee container idea- just drill holes with a hole saw. Sure it beats cutting tiny squares with a paring knife... Good upgrade!
