Of course all I can get my hands on is Tylan 200. Everywhere around me is sold out of Tylan 50 (back ordered) and this was the last bottle. (Has to drive 30 mins to just get a hold of this). I could only find a 3cc syringe. Any suggestions on where to buy a 1cc syringe? Any idea on dosage for Tylan 200? I know it’s less common. Yes same chick unfortunately. I havent noticed any lesions or anything else. Besides the day after i brought it home had a runny nose and kept blowing snot bubbles but was otherwise happy and healthy. The swelling just happened the night before last and yesterday. Which is when more mouth mucus appeared. The last 2 days it has gone down hill quick. The Tetracycline seemed to be working up until this. Though, It’s possible the dosage was too little because of being “gun shy” so to speak. It’s definitely very frustrating and sad, and I certainly don’t think I’ll be going to this breeder again. I just got some Ayam Cemani from her. They seem to be doing ok but we’re in same brooder before I quarantined. Gahhh. My older birds get Oregeno often so hopefully it will help keep them strong. But they currently aren’t in any contact with the brooder babies. And I wash well. I love in NC and would definitely appreciate you finding a lab for me. Once again, thank you so much!
I'm so sorry to hear you lost herHusband just informed me that BCM has passed. Do I freeze the body for lab? I have 2 more i suspect are ill. So going to treat them.

Eggcessive gave you good instructions for diluting the Tylan200 so you can use that.
Since you are in NC, you "should" be able to ask your pharmacy for an infant syringe and they will give you one. I've asked at Ingles before just to see and they offered several.
We have 4 labs in NC - Arden/Fletcher, Monroe, Elkin and Raleigh. I'll link the website too. Refrigerate the body and either take it yourself or mail it in. They should have a shipping label you can print and they will add that to your bill. I've not used the lab services yet, but several people have and found that they are also very helpful over the phone if you need to call and ask questions, I hope you find that to be true.

Hopefully the others that are showing symptoms respond to treating and you find out what you are dealing with. Please keep us posted.
