Five of my six, 27 month old , hens have a respiratory infection. They started Baytril, 22.7 mg yesterday. I had to bring one into the house yesterday because she was so weak and the others were attacking her. She is a bit stronger today but still wheezing badly. I put her back with the flock this morning but wondering if she would be better off inside. It's obvious she is still weak and you can see her laboring to breathe. I am inclined to bring her back inside but don't know if she would be better off inside or out with the others - they aren't bothering her today. She is eating and drinking. I am keeping a close eye on the other hen. Thanks for any advice you can give me.
