Cottonball, my sweet little white silkie, just started laying eggs a few weeks ago. Now she will not get up off of the nest, "growls" at us, and seems so determined to hatch a patch of straw in the nest box as there are no eggs under her at all. Will she sit there forever if I do not buy her some inexpensive fertile eggs so that she will eventually hatch some & then start to lay her own eggs again? Or will she find out soon that nothing is there? Thanks so much for any advice you may have for me!
