Thanks for the replies! I have seen one of my girls constantly opening and closing her beak as if catching her breath, but they have both been eating and drinking well. Also, I think their slight lethargy is because of the sudden "heat wave". I'm almost positive they have been sneezing more lately (or that's me being paranoid), and they have been making loud, random bok noises out of the blue. I have been giving them electrolytes and vitamins in their water, to help their immune systems, but do you think I should also consult a vet?
