Is it normal that a parakeet eats newspaper on the bottom of their cage i give them bird ssed every day too.and they still eat it.i dont know if are trying to make nest.please help?

Parakeets eating newspapers is a common behavior, but it is not advised to let them do so. Newspaper ink can be toxic to parakeets and cause health problems over time. They may be trying to make a nest out of the newspaper, which is why it is important to provide them with appropriate materials for nesting, such as nesting boxes and shredded paper.
