I have 4 jersey giant chickens, I bought them about 3 weeks ago. The previous owner was feeding them pellets and corn, but the hens don't seem very interested. They love weeds from the garden. I got them a hanging feeder and I kept throwing meal worms in it until one of the hens pecked into the feeder, but they're not eating the pellets. Like, at all. This morning they were just milling around making sounds instead of scratching like they usually do, and this was a couple hours after I had thrown out some more pellets and corn on the ground. Should I be concerned? They're usually busy scratching and don't make a lot of noise.
