I cannot think right now because I have birds dead and dying (Flock of 13) I can list the symptoms when I figure them out. Some have cracked and bleeding legs. There are small bugs flying around them. That's all I know. One died last night, and we thought the rest were fine. Anyway, I have some vitamin powder that I have never used and it is for bulk. Does anyone know a smaller dose for a 3-gallon waterer? These are the directions It is Durvet High Performance Poultry Pak-4 oz. I'm supposed to add the one 4 oz pack to 2 gallons of stock solution that would then distribute 1 ounce per gallon? Also, I have Terramycin in a soluble powder but don't know if that will help. It's all I have. It's a 6.4 oz packet. The directions are the 5-10 packs per 2 gallons of stock solution that meters at the rate of 1 ounce per gallon of fresh water. I'm sorry if I'm breaking any newbie rules, but my children are hysterical that their pets are dying, and I need to go take care of my acute situation. Then I will be back and give more info if I can.
