Giving a bird oral medication directly by mouth is risky as you can cause the bird to choke.
Tetracycline is not the best antibiotic to use when treating birds. Frankly, I would ditch it. Most broiler operations use tetracycline as a growth aid than they do to treat CRDs.
Penicillin can be given to poultry. Super Booster is usually readily available at most poultry supply stores and contains both penicillin and vitamins. You can also buy just penicillin in powder form that you mix with water to give chickens to treat CRDs. G&E in Edmonton sells it but only in a large bottle as it is also used I believe to treat cattle.
Mycoplasma is the medical term for CRD and Sinusitis is one of over 40 known CRDs. Anti-biotics will cure the symptoms of most CRDs but once a bird has a CRD and becomes well, it becomes a carrier. Stress may bring about an out break of CRD in carrier birds. Most general flocks have birds that are carriers but that does not mean your flock is a plague waiting to be unleashed. The majority of poultry vets will tell you that if a flock is properly managed, CRD should not be a problem even if you have a carrier in your flock.
Most CRDs are not lethal killers. They are much like the common cold. Only a few CRDs are a real concern, such as Infectious Newcastles' Disease and ILT.
I find Tylan is excellent at treating CRD. Baytril is too.
Tylan you can buy from G&E in Edmonton. Both can be bought from a vet but many vets don't prescribe Tylan. Baytril was withdrawn for use in poultry here in Canada by the CFIA a few years ago. Some poultry vets will still prescribe it but you must bring your bird in to be evaluated first.
Like your roo, I had a couple of roos years ago that began wheezing that got worse. The cold weather seemed to trigger it. One roo, even with weeks of treatment, never got over the wheezing and got worse. He was put down. The other I did take to a vet who prescribed Baytril Within 3 days he was back up on his feet as if nothing was wrong. However, he was never 100% well afterwards. He finally passed away over a year later.
If you have not already quaratined your roo, you should. My golden rule: If you try a treatment and don't see improvement within 3 days, try something else. Most anti-biotics for birds are given by mixing with water. Make sure that is their ONLY source of water so they will take in the meds. Keep the bird warm and away from drafts. Most treatments call for 5 days but better to go a week before stopping treatment. Full recovery usually takes 14 days.
To help your roo with weight, 2 tablespoons of tin cat food as a supplement. Cat food that is fish is best. Sick birds that will not eat grains will eat soft food. If you don't want to use cat food, a mashed up boiled egg will usually work also.
As for the turkeys. Sounds like you have an infected flock.
If you do not want to cull them and you decide to treat, I would look into a good anti-biotic for turkeys. Make sure that when you are doing your daily rounds that you do your turkeys LAST to prevent cross contamination with your healthy stock. If the disease persists, I would seriously consider culling the turkey flock. Especially as the majority of your birds are showing infection.
