My mama cockatiel has 2 babies that are 4 weeks old. She is so loving with her babies. Papa cockatiel is also caring for his babies when it comes to feeding and protecting them. But papa cockatiel sometimes goes inside the nest and plucks a few tiny feathers under the chick. This rarely happens. He isn't aggressive against them. He never pecks at the babies. But there has been tiny bald spots appearing in the chicks body. Should I take the babies out? Or should I leave them in the cage since they are almost ready to fledge and wean?
