PIJAC claims on its site the bill is being pushed hard by The Nature Conservancy and The Humane Society. Beyond hoping someone...
Females will go to the bottom of the cage and scratch around when they want to lay eggs but if you want to put the bucket it now that shouldn't be a problem. If it's in the cage with an open lid you probably want to check the dampness of the sand once a week or so (with high temps, low humidity...
