NO! Do not treat with sulmet and a wormer at the same time. Sulmet is the preferred treatment in conjunction with tylan 50 to treat coryza, but not with wazine or any other wormer. The combination would be too harsh on the birds system causing possible organ damage or even death.
Sulmet 12.5% soluable powder dosage is 2 tablespoons per gallon of water. Medicate at that strength for 2 days. Then reduce to half strength, 1 tablespoon per gallon of water for an additional 4 days. If your bird is not drinking on her own, you'll have to force the treated water in her. Be careful not to aspirate her and you'll have to give her the treated water at least 7-8 times a day to hopefully be effective. You can use tylan 50 injectable by injecting it into the breast muscle just under the skin (1/2cc for standards, 1/4cc for smaller birds) once a day for 3 days. Alternate injection sites...left breast, right breast, then left breast and not injecting into the same place.
Then wait several days after the sulmet treatment and worm your bird with valbazen liquid cattle/sheep wormer or safeguard liquid goat wormer (not wazine.) Both wormers are easier on the chickens system than wazine and they kill more types of worms than wazine.
Dosage for either wormer is 1/2cc for standards, 1/4cc for smaller birds and give orally undiluted. Repeat again in 10 days.
Again, I recommend the bird be culled and sent off for necropsy. You can contact your county extension agent, state department of agriculture or a vet to find out how to go about doing that.
