Why are my finches huddled in their nest and not moving much?

That can be a general sign of illness, especially if he is sleeping on the floor of the cage (it's hard to tell from your photo). Keeping him warm and eating and drinking can help, however since the behavior has been ongoing for a week it is best to bring him to a vet for a complete exam. Birds are great at hiding illness, so ruling out any issues such as nutrition problems, infections, illnesses, etc with your vet is best.

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.

Restlessness, picking or pecking at body parts, and holding a limb (whether it be wing or leg) in an abnormal way can all be signs of pain or discomfort. Sitting in a food bowl may be a sign Alex just isn't feeling well enough to perch or doesn't feel like she can balance safely without falling. Having Alex examined by a veterinarian who specializes in birds is a good step toward figuring out what is causing her pain. Your vet may recommend radiographs to see whether there is something going on that would explain her unusual behavior. In the meantime I would keep all of Alex's food and water bowls on the bottom of her cage and lower her perches to almost the bottom of the cage so she doesn't hurt herself if she has trouble balancing or grasping the perch. It doesn't take much for these tiny finches to hurt themselves so creating a safe cage space until she can be examined is a good idea. I hope this is helpful. Good luck with Alex!

It sounds as if your female may be sick and it would be best to bring her to a vet ASAP. It is possible she is exhausted from laying the eggs due to malnutrition, has an illness, or even has a stuck egg that is making her ill. Seeking veterinary care in person ASAP is best to try and get her feeling better. You may also need to separate her into a warm hospital cage until you can get to the vet to help make her more comfortable and reduce stress.

If Bonnie is fluffed up, not eating or drinking and very listless it is likely that she may be ill or injured and veterinary care should be sought. if all your birds are affected, it is possible they are all ill from something contagious, or the cage may need to be moved to a warmer/less drafty spot to help keep them warm enough. Keeping them warm, eating and drinking, and separating any visibly ill birds to a hospital cage until they can receive care is best to prevent the spread of illness.

It's possible one or both birds may be ill, especially if they are not acting normal and seem very lethargic. Keeping them warm and eating and drinking can help, but it is best to bring them to your vet so they can be examined and any more serious issues such as illness or injury ruled out. If one seems very ill or injured, separating the two birds into hospital cages can help until you can get into your vet.

In general, if the incubation does not begin within a week, the chances of the eggs hatching decreases significantly. It make be that the finches' parental instincts have not matured yet or possibly the eggs were not fertilized. You can dispose of the eggs and see if the finches have better luck on the next clutch. Best of luck!
