Happy to have you as part of our growing community! If they are 6 months, I would feed them layer feed. And if they are doing the "Egg song", you should expect eggs any day now! Also, if their combs and wattles are getting bigger and redder- they are about to lay. If you have any questions don't hesitate to ask or hop over to the Learning Center: https://www.backyardchickens.com/atype/1/Learning_Center
