Ok, so I'm new to chickens. I have 8 hens. I've noticed the last week or so that they seem extra hungry. They have access to chicken feed 24/7 and I throw them scratch during the day. I used the scratch to train them to come when they are called because I let them free range during the day. The past few days my girls run to me begging for food. I first thought they just wanted the scratch, so I started giving them regular feed instead. They still do it... why do they seem so hungry? Is it seasonal?
