Not as advertised and huge health risk to your birds if you put there solution in the pen. These are supposed to have the carved out bowl in the bottom for the eggs but instead it comes with a piece of styrofoam with a hole cut out 1st that’s not what is advertised online or on the product itself. 2nd putting styrofoam in a pen with bird notorious for chewing anything they get there mouths on is a bad idea could clog them up and kill your pet.

The boxes themselves are clean and nice. The hole is a bit small, but OK. The issue I have is that there is no insert beyond a styrofoam square with a circle cut out of it... and I don't see anywhere to buy the inserts. The Bottom of these should be concave so that the babies don't get splayed legs. I guess that's why these boxes are relatively inexpensive. They come with mounting hardware, which is nice, but the concave bottom is really a necessity and if you're going to make boxes that don't have that, then you should be selling the inserts.
