Hi everyone! We have an indoor call duck named Albert. He is 8 months old. We do take him outside when the weather is nice, but that's not often nowadays. We have noticed the last little while that the 'tooth' on the end of his bill has gotten longer, and curves downward. We aren't sure if it is hindering him at all - he still eats and drinks - but sometimes we catch him cawing with his beak closed. Has anyone encountered this in their ducks? I'm wondering if its because he is indoor, he doesn't have much to rub the end down on.. Any help / ideas / advice is greatly appreciated!! Thanks!
