I have 10 hens. I put a disposable cat litter box on the floor because my hens boxes are up way to high and the baby chicks will fall and break their necks. I placed the box on the floor with the eggs in it. The hens are kicking the eggs out of the box and not sitting on them. What am I doing wrong? It is summer time and it is hot I thought that was the best time to lay eggs and for them to hatch them. I need someone suggestions or help to figure out how to get them to sit and hatch their own eggs. The hens are about 8 months old and I didn't know if they were to young or what?
