My finch is fat, fluffy, and sleeping on the cage bottom. Is she ill?

It sounds like your bird is not feeling so great! Unfortunately, those are very vague signs of illness that you listed, so he'll need to be seen by a vet to try and figure out the underlying cause to get treated and feeling better. Illness, disease, malnutrition, parasites, infections, etc can all be potential causes of illness, so finding the right one with your vet is best. Until you can get into your vet, keeping him calm, quiet, and with easy access to food and water may help, but vet care is needed if he is showing these symptoms currently.

If the feather fluffing is only at night and the second bird is otherwise healthy, eating, and active I would not be too concerned, and adding a cage cover at night to keep the birds warm may help. However if it is fluffed up all the time, eating less, or showing other signs of illness, then I would schedule a vet visit and move the affected bird to a warm hospital cage to help it rest and rule out any more serious issues. The cage you have for both birds is also extremely small, so I would recommend placing them in a much larger cage that they can easily move around and stretch it and with some added toys to prevent stress and boredom.

Thanks for reaching out about Sunshine and including a photo. If after the 13 hours of posting, she is still lethargic, a veterinary visit is recommended. If she is cold, providing supplemental heat should improve attitude almost immediately. Birds are often fluffed when ill and conserve energy by being quiet.. Good luck.

That's a lot of changes at once for Dodo, and it's possible he could be a bit stressed out. Making sure Dodo has his own access to food, water, and perching spaces may help reduce stress. Birds do have periods of downtime during the day where they may nap, and they can do so as a group, so it may be you're noticing they're taking a collective nap, however after a bit they should return to normal activity. If anyone is constantly puffed, not eating or drinking, or otherwise appearing ill, removing them to a separate hospital cage, and keeping it warm and with access to food and water may help, in addition to seeking veterinary care.

Thanks for reaching out about Sky and including photos. Birds are typically fluffed when cold or ill. A veterinary visit is recommended, sooner than later. Providing heat support can give some aid but is not a cure for illness. As a new bird, moving to a new home can be stressful for a young animal, and suppressing the immune system, allowing subclinical infections to manifest. Good luck.

The birds pictured are parakeets/budgies. They both look normal in appearance. Sometimes, they will perch fluffed up a bit. This is normal as long as they aren't doing it all the time or have other symptoms. Monitor for lethargy, decreased appetite and loose droppings. See an experienced avian veterinarian for an exam to diagnose illness or injury in needed.

Thanks for reaching out about Mr. T. Being fluffed is not a specific sign for any illness, and could be just cold. Provide heat support in the 80-85 F range. Intestinal parasites or infections, metabolic (liver, kidney) disorders, nutritional deficiencies, inhaled or ingested toxins are just a few of the possible causes. A veterinary visit can help rule in/rule out causes. Good luck.
