I have 4 chickens who meander about on 1/4 acre, fenced. There's chick pellets (layers mash and developer feed) and water in the barn, and I put more in the yard in one spot. But the only takers seem to be the squirrels! If chickens have a lot of space, is it possible they are not 'finding' or choosing the real food, and may not be getting enough nutrition? I have one hen that's 18 mos, and lays daily, and 3 'babies' who will be at point of lay this month. My layer hen seems skinny, but the food is available all the time. Should I worry? Should I restrict their roaming so they eat more of the pellets? They all seem like picky eaters too. They love mealworms, and macaroni, but show no interest in other vegetables, or leftovers. I had 2 pumpkins out there and they barely touched them. (squirrels again had fun - I have the fattest squirrels - I wish they could lay eggs.)
