So, what do you guys think?

Its just so weird that they both seem perfectly normal during the day. Cookie even walked on her foot a bit today while they were free ranging. But when I got out their worms to lure them back to the henhouse she hopped and flew.
Our chicken breeder friend (is thst what they're called? Chicken breeders?) is thinking Coccidiosis. Nobody has grey eyes, their skin is normal and they dont seem to be losing weight or body mass. But I did find bloody poop when cleaning today and they have been playing in wet, yukky mud (it makes them happy. Weirdos.) So they now have Amprolium (Corid) in their drinking water and I guess I'll keep watching them to see what happens next.

I spoke to a vet and had 2 other experienced chicken people come over and visit my flock, and nobody seems to think we have Mareks because of the presentation of signs/symptoms. The fact that the rooster has very pale legs and the hen is very droopy raised a red flag, plus someone in the flock (I don't know who) had some bloody poop. One person said that the two sleeping on the floor together is called "huddling" and that's a tell-tale sign of Coccidiosis. So I have been putting Amprolium in water since Wednesday, and my hen (Cookie) is all perked up, walking more on her damaged leg (which may be an injured tendon) and seems to be on an upswing. However, Pancake, my rooster, is still sleeping more and huddling with Cookie and just doesn't seem like himself. He has also started sneezing, and one of my Buff Orpingtons (JodiMills) is now sneezing and coughing and had goop eyes yesterday. No gurgles and no snot on her beak, but I don't want to wait for that to develop, either. I've read where I can still dose them with Tylan 50 orally, but wanted to double check on opinions of doing both at the same time since the Corid (Amprolium) is in their drinking water.

It's possible you have more than 1 thing going on there.

I believe corid and tylan can be used together, but I'm not positive. Is the tylan injectable/liquid or powder? If it is water soluble that is not going to work as corid can be the sole drink they get for the 5 days. I think it is poultry vitamins you've got to hold off on while dosing with corid. Hopefully someone with more sound knowledge will be along to advise.

I suspect you would be best to finish out the corid treatment, then start the tylan.
Good luck!

I'm sorry that you have some sick chickens.
The Corid is fine to give to the whole flock if need be, but for the Tylan50 I would only treat those that have symptoms of respiratory illness. (sneezing, coughing, goopy eyes).

Injectable Tylan50 dosage is .25ml per pound of weight, given orally 3 times a day for 5 days in a row.
It can be given in conjunction with the Corid (Amprolium). If your rooster is one that you are treating for Coccidiosis, you may also need to encourage him to drink or syringe the Corid solution into him. Sick birds don't drink very well and can become dehydrated - he also needs the Corid water.

Hopefully with treatment he will begin to recover. Keep in mind that not all respiratory illnesses respond to antibiotic treatment. Recovered birds and those that are exposed can also be carriers of respiratory disease for life depending on what you are dealing with.
