I was down to one hen and just introduced 2 pullets. My hen lays every other day and since introduction her eggs are broken. They are pecked and broken but not eaten. I believe I have identified the pullet doing it (egg on beak). She won't break the pullet eggs, just the hens. This seems to be about breaking the outsiders eggs and not their own. I have had this happen before when introducing new birds. New birds go after the eggs of the original flock. Have others seen this after introduction? The selective breaking? I have read the tips on how to stop egg eating but not sure if it will work since this seems to be an aggressive move. May have to cull. Thoughts?
