Hello, I recently bought a bird (well 2) for the first time and they are 5 weeks old. I notice that after feeding he was breathing weirdly as in making heavy noises and beak clicking. Then it stop, it only happen this time, he also sneezes rarely rarely (like 2 times, one each day in the morning(so2days)) but in one of those days he sneezed and had a tiny clear liquid discharge (like tiny water drop). Should I not panick? Or is this normal?
