Help. My 6 year old and I have a pair of adorable peachfaced lovebirds. The hen laid one egg. I didn't know what to do, went to a pet store, bought a little nest and put the egg in it. She refused to sit on it. While we were on vacation, she laid 3 more eggs in the cage bottom and is sitting on them. I am afraid to change the cage bottom, but the eggs are sitting (and so is the hen) in unsanitary droppings for two weeks now!!!
what should we do? Do we need to provide an additional heat source?
