dosage for di-methox?

[Ariesmom]

I have a question on how to dose di-methox to one rooster and a hen...he has symptoms of coryza and she does not but they have been together all along. I guess I'm wondering should I treat her even though there are no signs. I definitely want to get him better and was wondering if anyone knew how to dose it, either by the gallon or even better, if I could do it direct dropper. The package says it treats 50 gals...it also specifies not to use in chickens older than 16 weeks...why is that?

Sulfadimethoxine soluable powder (Dimethox) dosage is 1/8 teaspoon per gallon of water for 7 days. Make a fresh batch daily. Are you sure your rooster has coryza? Is there a foul odor about the head of the rooster? If so, it's definitely coryza and I would dose the hen as well, it is contageous. There is a 5 days slaughter withdrawal after the last dose.

thank you so much for your advise....he does smell awful around his head!!! The only way to describe it is like a stinky hound dog that rolled in something dead! The hen he is with has no symptoms at all and I do have one more question....unfortunately I did put all of my birds together for one whole day until I noticed he was ill....I quickly removed him and the new hen from my existing hen and duck...so do you think I should treat my others that were only exposed to him for a day? Or should I wait and see how they seem over the next week before medicating? After treatment are any permanent problems I should be aware of ie...not let them hatch eggs or us eating the eggs etc??

Incubation period for coryza is 1 to 3 days and the course of the acute disease stage is 4 to 12 weeks.
You will possibly see symptoms with the others commencing after the 3rd day, most probable at first weeks end, increasing as days pass. If you see these symptoms even in one or two chickens, I would treat ALL of them. Even after treatment, all your chickens will be carriers for life. You will have to have a closed flock...none in, none out, no exception. The eggs will be safe to eat. Hatched chicks will be carriers.
Personally I would cull the rooster and hen he's with, and watch the rest of your flock for symptoms. If they show symptoms...cull. You would have to decontaminate EVERYTHING with bleach or oxine; including waterers, feeders, tools used in the coops or pens, their houses, the clothes and shoes you've worn etc... You can use agricultural lime on the soil. Wait several months before introducing new chickens into your pen/coop.

I don't mean to keep nagging you with questions but is it a death sentence for the chicks to be carriers or is it ok as long as I don't sell any off? Also, is my duck at risk too...he is my daughters pet and she would be broken hearted if he got sick too. And I'm confused with the incubation period you mentioned....I put the new rooster and his hen in with my 2 on Tuesday afternoon and by Wed I pulled the 2 back out to be treated on the other side of the barn. I had been giving Duramaycin in the water of everyone as well as vitamins but realized with coryza it's not the right antibiotic so I switched today to the dimethox for only the 2 quarantined birds. Do you think if my other 2 healthy birds (duck and hen) don't show any signs by the end of this week we're ok and don't need to treat or do you think I should do the same dimethox as the other sick 2 even though they haven't shown signs? I'm also confused as to why the hen he is with is completely fine showing no signs of sneezing or crusty nose at all........I looked up coryza and the only thing he is displaying that matches up is the smell and sneezing...he is not lethargic or droopy, he eats great, crows all the time and isn't swollen in the face or dull in his comb at all... All this chicken disease is making me go crazy!!!!! I just don't want to kill anything...I get sad if I hurt a pretty bug let alone kill one of my own pets!
