My little polish hen has been acting off the last day or so, today she wouldn't come out of the coop. I brought her out, brought her in the house and one of her eyes seemed to have some crusty discharge and was closed. I rinsed it with warm water and left her on the bed with me for awhile then put her outside in the sun. She's not walking around. She does preen - but...... I gave her some water [which she drank] and some pumpkin pie [which she ate], but she just doesn't seem to be herself. Her head seems to droop - it's like a little kid when they're falling asleep standing up. Should I bring her in? What should I do?
