Red feathers but puffed up

I agree with Cody and recommend you take your budgie into an Avian Veterinarian for a proper diagnosis.

How long have you had her?
What is her name?

The purpose of this forum is to promote the BEST PRACTICES in the care of budgies for their optimal Health and Well-Being
Locating an Avian Veterinarian

Avian Vets have special training to determine the cause of symptoms resulting from illness or trauma.

When you rely on anyone who has not had training in Avian diagnosis and care, you may be delaying effective treatment.
This can prolong suffering that may be avoidable.
The bird will often require a more intense, prolonged treatment with a poorer chance of full recovery than it would have if you seek prompt professional diagnosis and treatment at the first sign of illness.

If there are no Avian Veterinarians near you, the next best option is an exotic pet veterinarian that has experience dealing with small birds.

Be sure to wash your hands very well before and after handling your little bird. Along with a vigorous rubbing together of your hands, be sure to get under the fingernails as well. All kinds of creepy crawlies can hide there 🦠. I've actually found that the best tool for cleaning under fingernails to be slanted tweezers. They work like a dream. Not to mention you can use them to make your eyebrows look stunning lol. Hygiene is important not only to prevent introducing pathogens, but also it prevents them from bouncing back and forth, which can happen. It will also protect your health too. Although there aren't alot of illnesses birds and humans can share, it's better to be safe!
