Hello I have a small flock of 6. I raise for eggs and consider them pets. So with that in mind as pets I I want to do everything for quality of life and address health issues where I can. I am in middle of treating bumble foot, just had to start dewormer for round worm when I notice they are starting to show signs of second round of respiratory infection. (About month ago) was first outbreak and was given tylan. The vet first time gave tylan for all. Second round started vet said seperate a few days and gave one bird another round but would not for all birds. Well today during foot bath soak noticed clear snot on another. Am worried the vet will start to think I am a hypochondriac when I call Monday to ask for second round of anti biotic again. Is there anything over the counter I can get? I would imagine with all three issues they are immune compromised. Any advice would be great! Feels like last month has been one thing after another. And surely chickens are over me fussing over them and would like to be left to do chicken things.
