all i can say is yes they do! We had no idea what was going on with our little girl...I even posted a question about her digging, or well trying to dig, all the time, when there was nothing to dig into in her cage....well, my husband just called me and she's laying eggs.
Now i'm concerned because we didn't prepare for this, we didn't up her calcium, we didn't make a box for her to lay them in and now i hear that they could become egg bound.....scary!
