I have 3 chickens who have laid eggs very consistently until recently. I was getting 1-3 eggs a day and rarely went a day without an egg. They are 18 months old and lohman Browns. I don’t know if maybe they have decided to start laying them in some random other place I can’t find or they are just not laying.
Hens go broody when you don’t want them to… and won’t go broody when you do. 



Not always, but usually. 
Feed them back to your birds or toss them. Getting sick isn't worth a few eggs.
