we are new to birds so I apologize if this is obvious. We have two parakeets that we got 9 months ago for my daughter. She cares for them very well and they’re happy and playful birds but one of them is worrying us. Her feathers become immediately saturated when she is in the water and her posture does not look right. She sometimes seems to shake or quiver and closes her eyes a lot more than the other parakeet. She also seems lethargic. She is still eating and drinking but I’m wondering if she is missing something in her nutrition or if she is sick?? Trying to avoid another vet bill as we just unexpectedly spent a ridiculous amount on two dogs last week. Any help or advice would be greatly appreciated!
