For the last few weeks one of my chickens hasnt been slow to leave the co-op in the morning and isn't excited about eating. She makes noises and is alert and will run alittle bit when they are free in the yard. ( They are in our garden area most of the day they only get out in the yard a few hours in the morning and then again at night. I gave them yogurt a few days ago and she seemed to eat a good amount. And I have seen her eat some other food but she doesn't act like the others when she I feed them. I have had her for about 5 months. She is only a couple of years old. I have caught her once in the morning and her crop didn't feel full. Her poops are watery.
