I am currently treating, by injection, a 13 wk Buff Orp with Pen-G for an infected injury. Recently, she and her 4 'sisters' (2 cochins, a silkie, and a Brahma) are showing increasing signs of respiratory issues like sneezing, head shaking, etc.. I plan to treat the rest orally with Tylan. Can/should the Buff also take Tylan while on Pen-G? Thanks, folks, for your consideration and help. And I'll echo what others have said previously: the BYC community is an invaluable and comforting resource! -h
Welcome to BYC. Since penicillin is not right for respiratory disease, and since Tylan is not that great against wound infections, I would probably use both if i felt it necessary to give antibiotics for the respiratory symptoms. If a vet is available, you may be able to get Baytril, which would treat both well. Since respiratory diseases such as infectious bronchitis, MG, coryza, ILT, and aspergillosis can be viral, bacterial, or fungal, antibiotics won't always have an effect on the symptoms, but may help to prevent secondary bacterial infections. Here is a good link about respiratory diseases to read and compare symptoms: http://edis.ifas.ufl.edu/ps044
You might also consider that fungal infections occur in poultry during the wet season if humidity is high and ventilation is inadequate. I've used Oxine a number of times as described in this article, and it is very effective: http://poultryone.com/articles/respiratory-html I hope conditions improve quickly for you and your birds.
