My chickens are yr old and I have tried everything to make them eat their pellets( only given them pellets all day, using crumbles mixing them with seed.. They just left them) I guess they just don't like them or their spoiled which is totally possible . Any advice on how to make them eat it . I give them scratch and and extra greens and snackers like oatmeal on cold days or mealworms... They lay wonderfully so I don't think they are unhealthy just picky. O and another thing is it possible for a chicken to be naturally skinny?
