These are three years old and pretty much always in the play pen. Sometimes they will roll them so much they will be in a 1 foot hole, and once in a great while they will even bury them (I use the deep litter method in the pen, 2 feet of sawdust)
I think we started with 1/4" drill bit, put seeds in and shook to see if any came out. We may have ended up with 5/8" but I can't honestly say for sure.
These are sturdy G2 bottles, I'd never expect the new light water/pop bottle plastic to hold up at all.
My prototype was a plastic coffee can. Way too big for them to roll...
Take the corn out of the food hopper!
