Yeah I have had issues with aggressive production layer types too. Let the flock see them but do separate for 3-4 days so the chicks get more mobile and learn to follow the hen's directions better, they are slow and kind of dopey the first few days.Thanks for all the wisdom. I have had difficulty adding chicks or chickens to this flock. The gold comets are a bit aggressive. I am hoping the broody hen can do better than me and the integration will go better.
If in doubt separate longer, many folks use baby pens for a few weeks before completely mixing them and often doing it when the flock free-ranges is the best time for their initial introduction, the older birds will quickly wander off instead of staring/obsessing over the chicks all day.
