Thanks for the replies lads it's just that the past 2 years I,ve been working shifts and was looking for ways to make things easier when setting the birds up on a Friday,in the past I've usually cleaned all the boxes and bowls of nesting material and then stood the bowl on it's edge against a corner of the box but I was thinking if they don't have access to the bowl all week then wether it was turned up or down shouldn't make much difference or would it?
