Just a few questions regarding an egg laying bin. Checking the size of the bin, what would be the correct size. You place it in your existing cage mine being 18x36. Do you remove the plant in the cage that you have now. I am saying that because there would not be no room for the bin. Could you use another cage for laying. Don't know if she would be comfortable with that. This would be for non fertile eggs which I presume the same for fertilized eggs.
