I have a silkie hen who is a hog when it comes to food. I keep her on laying mash, however she flew into the pen with some of my ducks, and has eaten alot of whole corn, her crop is tight, and full. She is acting listless, and weak. Does anyone have any suggestions as to what to do? I thought about taking an eyedropper and squirting a little cooking oil down her throat to maybe lubricate it, but I don't want to harm her further.
