New flock of 9-11 week olds. Salmon Faverolle, hanging by itself, sleepy, still eating and drinking just not as energetic as the others. They have been on Corid for 4 days (1&1/2 tsp in a gallon of water) because we lost one chick the first night and another was popping bloody (she's gone, we took her back). Maybe I'm being paranoid, but i feel something is off with her. Should i worm her too, just in case?
