hi folks need some help. My 6 month old chickens don't like any kitchen scraps or even their own food, which is organic layer crumble (we've tried pellets before as well, they hate that too). They free range for about 5 hours a day, and almost all day on saturday and sunday, and they peck around and eat things in the garden. They do like sunflower seeds, scrambled eggs, oatmeal. But they don't eat any veggie type greens. I was worried already until one of our chickens started laying eggs with a soft shell (calcium deficiency). Any advice on how to get them to eat veggie scraps, or even their own food, would be greatly appreciated. thanks!
