Bird keeps sitting on her egg
Hi so about a month ago I got a pet dove and then a one or two weeks later she kept sitting in the cage the whole day and we were confused why. Then she layed an egg and left it and 2 days later she layed another one. She’s been sitting on that egg since the day she layed it and barely gets out of the cage. We don’t think it’s a baby egg so is this normal? What should we do?
