they have not laid eggs for over 2 months. Oyster shell is what I need for them to lay right? They have laying pellets and I dont give scratch to them. We cant get to the store because my mom and her b/f have to use one car since my moms engine went in hers. the feed store opens at 8am and closes at 5pm. My mom is going to the feed store on her way home that is next to her work. Other then laying pellets what else do I need for them to lay? They are indoors and the temp downstairs is around 70F. They are next to a window where the sun rises in the early morning.
