So misty had 2 eggs 3 months ago. She's just laid another one. We don't intentionally breed them. We take the eggs out and put fake ones in. This time we didn't know she was pregnant, Ronnie just started really viciously attacking her on the floor with his wings out. We put him in the cage, and she started laying an egg. Might be worth mentioning, she was in a cardboard box at the time. They love to shred and play with cereal boxes etc but could this be encouraging nesting? Put them to bed now and they seem fine.
