Just inherited 4 chickens from a neighbor. Have had them for two weeks. The 1st week was fine and they layed pretty well. 9 eggs in 7 days. They have a new coop which is enclosed. (their old coop was open chicken wire with an upside down plastic bucket.) They have laying boxes with straw in them. The issue is that when they were in the old coop they layed, but did not eat their eggs. Now they are here they have started eating them. (I have watched all 4 fight over an egg before I could get there to rescue it.) We added wooden eggs to encourage them and that is when the eating started. Any advise?
