Is that cheese cloth over the grates? I know some use it for easy clean-up. How does it affect the chicks walking, as in nails getting caught in it? That's a nice batch of eggs you have!
I hope your Daughter is able to witness the pip, zip and hatch process of her 3 eggs. Much success for her and her project. I'm sure she will look back on this experience with fond memories of how Mom stuck with her, but allowed her to do by herself. Blessings to you both!
