Silkie not eating, but obsessed with water...

Noticed her being a little less interested in eating over the past three days, but now she shows no interest in her favorites. She seems lethargic although her wattles are even darker than her sister's- super dark red,purple. When she is lively is when she sees running water, then she runs over and drinks like she hasn't had any water for days when in fact she just spent ten minutes at her water dish drinking.
Kind of seems a bit wobbly on her feet. Any ideas? Will try some force feeding in the morning with some yogurt/honey.
