OK, all you folks with much more knowledge than me, I've got a d'anver hen that is acting off. She usually the first to meet me in the morning but she's hanging back and hunched up. She's loosing weight and hiding under the ramp. I gave her mealworms, grit,oyster shell, crumbles,and she rejected them all until I gave her a cucumber. I started them all on corid yesterday, anything else I should be doing?
