kakariki paralised foot
we have a 1 year old kakariki parrot.
today it woke with a paralysed foot (he is holding it in a club foot position) and is dragging it around.
The bird lives inside and is handled regularly.
he has not had a change in diet.
he has not been exposed to chemicals.
he has not had any injuries.
no new birds have been introduced into his enclosure.
he is very quiet, as apposed to his very loud self.
can you please help me with what could be happening, what can I do to help him?
