Hi everyone, I've had chickens since September and over the winter the number of eggs being produced dropped drastically. Some people told me that was just because of the cold and they would begin to lay more in the spring. However, I've been finding what looks like yolk and pieces of shell in their nesting boxes, and I'm scared they're beginning to eat their own eggs. Is there anything I can do get them to stop? I've been mixing up their diet plenty of fruits and veggies, some leftovers, meal worms, cracked corn. Is there anything else I should be doing?
