Testing your birds is very important to enusre your birds are not infected by contagious diseases, and also to reduce the risk that you or somebody else get infected by Chlamydia causing psittacosis / ornithosis in humans.
You can now do it your self at home by your birds.
If you find "positive results", here meaning that the tests show up indicating an infection, we advice you ro contact the veterinarian to have the right sort of medicine subscribed.
LOOK AT "HOME" to buy tests online!
Kind regards
