Hi I have 25 chickens. 14 that are laying and 11 that are chicks. So I just got 6 more chickens. 5 Leghorns and 1 I think is a rhode island red. I just started getting about 9-12 eggs a day. The Leghorns we think are eating some of the eggs. We will find 2-3 broken eggs at night. How do you stop them from eating them?
