I kept my sick hens with the flock. My reasoning may sound stupid, but I felt if one is sick the others must be as well. You can also rub the VetRx on their eyes. I just used a spray bottle because it was easier for me than to catch and hold the sick ones. Once I started treating them with Vetrx they did start eating after a couple hours and didn't start drinking till the next day or so. I'm glad you got Vetrx! I wish your hens the best of healing!
