My zebra finch is weak and sick after laying eggs. What can I do?

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.

3 hours without eating isn't a major concern, but if Pepper is continuing to worsen and isn't improving with home care, it sounds like she needs to be seen by a vet. Unfortunately, you already seem to be doing all of the at-home care that would help without further examination to determine what is going on with her. If she just laid the eggs, that is a stressor on the body so she could just be quiet and recovering from that, however if she doesn't perk back up, or seems to worsen, then trying to find a vet near you is best, even if they don't specifically see birds.

Thanks for reaching out about Piper. You need to see a veterinarian as soon as possible even if not an avian veterinarian. Heat support can give aid but is not a treatment. Calcium deficiencies are common reasons for egg binding, but just giving oral medications won't be enough. You need to see a local veterinarian, even if this means an emergency visit today. Good luck.

If Fifi is acting weak or sick while trying to lay an egg she needs to be seen by an avian veterinarian. Egg binding is when a bird cannot normally pass her egg and can be a life threatening condition.

Thanks for reaching out about your finch and including photos. A veterinary visit is recommended but understand if one is not available, but only limited things can be done at home. Weakness can have multiple causes, with infections being only one possibility. Provide heat support in the 80-85 F range can give some support. Finches eat primarily seed but also need a vitamin/mineral/protein support in the form of a wide variety of vegetables. Provide a soft bedding/towels on the bottom of the cage to protect if falls. Good luck.

Thanks for reaching out. Sitting quietly, fluffed on the bottom of the cage is not an indication of laying again. It is more probably a sign of illness and should see a veterinarian. Wheezing and respiratory clicking sounds are an indication of a respiratory infection, necessitating the need for systemic antibiotics. The second budgie, loosing feathers, could be a stress molt, but several viral disease could also be the cause. See your veterinarian. Good luck.

I am sorry karani is not feeling well. I would recommend trying to get her to a vet as soon as possible. My concern would be hypocalcaemia. This is where their calcium is low in there blood stream. Birds are prone to low calcium because they used a lot to make eggs and bone health. I would recommend trying to force feed slowly and add in a calcium supplement. keeping her clam and relaxed is also important
