I have a two year old Barred Rock who was fine yesterday and is gasping for air today. I went to TSC and got Duramycin-100, as well as VetRx Poultry Aid and Poultry Nutri-Drench. We have brought the hen inside now and she is in a dog crate close to the air-conditioner. My question is how much Duramycin-100 should I give her, how often should I give it, and for how many days? It is an injection formula. Thanks!
