I treated her and two others for 7 days with .5 cc twice a day with tylan 50 but they still sound a little wheezy so they are still separated from the flock. It's been 3 or 4 days since I stopped. And don't worry, I will NEVER be forcing anymore liquids after that. She seems to be doing ok but like I said, they're still a little wheezy. They sounded horrible before I started the antibiotics but showed no signs of weakness and were quite lively, and still are. 2 to 3 days in and they were about 80% better but then kind of stopped improving. I don't really know what to do. I'm afraid to give them more antibiotics because they have already gotten a lot. I have tylan powder on its way in the mail so I have it on hand if I need it like, if any of the other chickens were to get sick I wont have to inject them.
