try corrid, they sell it at Tractor Supply Company stores. You have to act ASAP.
If you can't find it at
Tractor Supply, try Agway (if you have one). My TS didn't carry it & no one seemed to have heard of Corid (Corrid?) but the gal from Agway knew
exactly what I was talking about. She was out of it, but ordered me some for my Medicine Kit. I was able to get some Sulmet (Sulfamethazine Sodium), which covers Cocci. It comes in a liquid form, white plastic, 16oz bottle & you add it to their drinking water for 6 days. (less than $10)
From the label "Sulmet (sulfamethazine sodium) Drinking Water Solution, 12.5%. Convenient once-a-day dosage in drinking water. Prepare fresh solutions daily.
In Chickens, for the control of: Infectious Coryza (Avibacterium paragallinarum); Coccidiosis (Elmeria tenella, Elmeria necatrix); Acute Fowl Cholera (Pasteurella multocida); Pullorum Disease (Salmonella Pullorum).
Dosage & Administration: Poultry--Add 2 Tablespoons (1 fluid oz) to each gallon of drinking water
if Infectious Coryza (in chickens): Medicate for 2 consecutive days.
Acute Fowl Cholera & Pullorum Disease (in chickens): Medicate for 6 consecutive days
Coccidiosis (in chickens & turkeys): Medicate as above for
2 days [ie: day one = 1 fl oz med/gallon water & day two = new batch 1fl oz med/1 gallon water]
then reduce the amount of Sulmet Drinking Water Solution to one-half for 4 additional days [ie day 3 = new batch 1/2 oz med/gallon water, same on days 4, 5 & 6]
You shouldn't eat the eggs during the treatment, or for at least 10 days afterward. And because the risk of excessive dosage could be toxic for the birds, I wouldn't keep the eggs at all.
(I originally thought I might just scramble them up and give them to the girls as a treat, but after reading the label warning, I thought better of it. 16 total days without fresh eggs is a small price to pay for their health even though I hate to waste the beautiful eggs they work so hard to make for us.)
I hope this helps!
