Hi everyone,
I have a budgie who has just recently started exhibiting rather peculiar behaviour. That is to say, stranger than normal as she was pretty bizarre when I got her.
She is a young hen, violet yellow face who has had chicks in the last 2 months. The chick are blossoming however, she began to attack them once they left the nest and it was pretty vicious. So much so I separated the chicks from my modest flock. She began to run up and down the bottom of the cage, turn somersaults in all corners and kicked all the seed out of all the bowls. She did this until I got tired of cleaning up the mess and paying for wasted seed. I put her in the smaller cage with my other hen (who was also attacking the chicks) and placed the chicks with the males in the big cage. The males love the chicks and treat them rather well. However, the violet hen is still exhibiting this mad behaviour where she is constantly picking up the seed or water container in her beak and up-ending them.
I wonder if it is possible for budgies to develop mental illnesses and I am obviously worried that my other hen will starve to death/dehydrate because her cage mate is getting rid of the food and drink.
Any help or advice would be appreciated.
