I will agree that hanging them solved my problem too. However I know that my chick feeder & waterer didn't come with any way to hang them. Once I got my bigger 11 lb feeder & 3 gal waterer, the problem was solved because I could hang it. I do have a couple of recommendations that have worked for me:
-Place a bit of hay on top of the pine shavings. I feel pine shavings are better to use than hay for the most part because they don't decompose nearly as fast, however a small amount on top of the pine shavings really helps to kinda hold them all down, like a net.
-I second a previous reply, and that is to elevate the chick waterer. Just make sure whatever you use to elevate it provides a step up around the waterer too so that they can reach it.
I tried making about a 2'x3' section of the floor out of just 1/2" wire mesh and placing the waterer on it but somehow they just managed to drag pine shavings all the way over to it and fill up the dish.
