No I do not know about a laying bin? I have done some research about something like a laying bin sorta speak. Most things I have researched are food habits, heating, a cage ( I had her in a 12x12x18 glass cage had no idea they didnt like glass or small cages so I upgraded her to a 24x24x48 cage and she seems to love that a lot more with all the vines and plants i put in there. I am worried that she is older than I thought and she may be pregnant! How can I tell she is pregnant and is it true they can get pregnant without a male? I read that somewhere but not sure if its true or not?
