Q - My mynah occasionally sneezes. A - Yes this is normal. Mynahs get irritants in their nasal passage just as we do. When sneezing is persistent or coughing occurs and the nostrils are not clean and clear, then the bird is ill and needs a veterinarian's attention. You will just have to experiment.
Some birds play only with loose toys they can carry around when they are outside of the cage.
Just want to let you know that Squeek doesn't care for toys at all. I have tried putting in toys many times but all he did was looked at it but won't go near it. One of them finds a large feather during a molt, grabs it and beats it around picking it up once or twice. Then it's over, the interest last a very short time. The same with a toy, they may pick it up and carry it around once and then that's it.
