This is my first year owning my cockatiel and she’s gone through two molts (or i think it’s a molt) since february 2021. She first was loosing about 20 feathers a day for 3-4 days during the summer and now in January it just started again. It’s mostly little feathers but i did find a tail feather and a couple big ones today. Is this normal? I think she’s about 7-9 years old (we don’t know because she’s a rescue) and she’s on a pellet diet.
