My cockatiels are picking feathers, trembling, and have dirty vents. Are they sick?

Updated On September 23rd, 2025

I recently received 2 cockatiels, they are still unfamiliar with me. But I've noticed that they're picking on their feathers and many long ones have fallen. The female often lifts one of her legs and hides it behind her. They both puff up and tremble and they have poop under their vent. Are they sick? Or just nervous around me and their new environment?

While it can take some time for birds to settle in, they should not be losing lots of feathers, acting lethargic, or have stool or other materials stuck to their vents. This is more likely an indication of an issue such as too many treats/snacks, underlying illness such as parasites, poor nutrition, infection, etc. If both birds are affected, having them treated for parasite and examined by your vet is a good idea. Making sure their environment is clean, warm and draft free, away from any stressors, and they have access to fresh food (removing any snacks or treats that could cause diarrhea) and water may help, however if their symptoms continue, vet care is best.
