I have the Murrays Best First Aid. It has included VetRx, Vetericyn Poultry Care, and Blu-Kote. Also a few other small things like electrolytes and a bandage. I would like to add to this kit. I feel Premo Poultry spray looks good. Since I consider vitamins to be like medicine, I am looking at Poultry Cell. What do you think of these additions.
