Bird in sticky trap. How to stop pecking? Will feathers grow back?

I would separate the birds for a few days with the heat lamp just so your healthier bird doesn't overpreen or stress out your other bird further. It is also a good idea to seek veterinary care in person ASAP to make sure she doesn't have any lasting injuries from the fly paper, stress, or anything used on her feathers, especially since she is showing so many general signs of illness.

Poor Precious! The first step to growing her feathers back is to figure out the underlying cause behind why she plucked them and to change it. Health issues such as parasites, malnutrition, infections, illness, etc can cause feather plucking and loss, so scheduling a vet visit first is a good first step to make sure any underlying health issues are treated and she is healthy enough to regrow her feathers. Boredom and stress can cause excessive feather plucking. Making sure she is in a clean (the bottom of that cage need a scrub!) and stress-free environment away from other pets or people that may harass her is best. Adding in enrichment such as toys she can chew on or play with, a play pen she can climb and stretch on, or spending time playing and interacting together can help with boredom. In some cases, the feather plucking becomes a habit and needs to be stopped with the use of an Elizabethan (cone) collar or flight-suit to protect the body from being plucked. Feather regrowth takes time, so even with these changes it may be several months before you see them start to grow back in. However, keeping up with enrichment and health issues can help ensure they have a chance to come back.

Thanks for reaching out about Tweety. Providing heat support in the 80-85 F range can give some aid. Monitor food and water intake. If there is the possibility of internal damage, a veterinary visit is recommended to assess. Good luck.

Thanks for reaching out about Kiwi. Birds are typically fastidious groomers and will groom themselves. But, warm water and a mild soap such as Johnson' baby shampoo or Dawn dish soap works well also. If bathing, provide a warm environment at which to dry. Good luck.

Thanks for reaching out about Bangaram and including a photo. Psittacine Feather Destructive Behavior is common in parrots, but the difficulty is acquiring a cause. Stress/behavior is common a nd can consist of breeding, nutritional or environmental stressors. Diseases can also lead to pulling feathers including infectious diseases (viral, bacterial), metabolic disorders (liver, renal), skin diseases and others. A veterinary visit is recommended to assess and try to determine a cause. Diet and husbandry practices need to be reviewed with a veterinarian experienced with birds. Some diagnostic tests will probably be recommended and necessary to come to a conclusion. There is no topical medication that is going to cure or even stabilize this condition. Good luck.

Thanks for reaching out about Robin and including photos. Feather picking behavior can be due to multiple causes including stress, feather parasites (lice, mites), metabolic disorders (liver, kidney), infectious diseases (viral, bacterial), contact allergies and others. A veterinary visit is recommended, and you might have to utilize a hand towel to restrain and transport to a travel cage. As for trust, that just takes time, especially if not originally hand fed. Keep movements slow and deliberate. Good luck.

Make sure she has a balanced diet consisting of a pelleted diet, a fortified seed mix and small amount of fresh greens, fruits and vegetables. Provide a mineral block and/or cuttlebone. You can provide a birdbath or mist her with warm water a couple times a week to promote preening and healthy plumage.
