Was wondering if anyone ever used a Sterlite stackable plastic storage bins for Pigeon nests?? They make white ones with 3 closed sides, not like the Blue ones that I took a photo of. I was thinking plastic because they come apart & can be washed/sanitized easy. They also have a front dip, were they dip down, the Squabs wouldn't beable to fall out also + The Dimentions of the inside is 12" Deep X 16" wide & about 12" High or so inside the Bins...... I was just wondering if anyone ever used them & if there are any pros or cons to using them......
