no it is not normal. he could have a blockage from canker or sour crop or even something else, you need to tell more about the age of the bird and what his dropping look like, his eating and is overall demeanor.Okay, I'm not sure if he's foaming at the mouth, but he's blowing bubbles around his mouth. We just got done feeding him some peas and he started standing and stretching his neck. Is he having trouble swallowing? Breathing? Is this normal? What can I do?
