Urgent My cockatiel is walking with one foot

[Alireza]

Hi
My bird was very quiet today and he was holding one of his legs a little up at morning but he could walk without problem so I tough it's normal like when he is sleeping but now I saw that he can't walk easily and he is not using his left leg. I will go to a vet immediately tomorrow but until then ... Anyone know what is his problem and what should I do ?
There is no bleeding No injury ... his leg looks normal.

UPDATE : He is walking better than before but he is carrying his weight on the right leg more than left. He is not putting pressure on the left leg. Also when I put him in his cage he immediately stayed on his right foot and he was unbalanced at first !!!

I hope he's okay. Could he have caught it on something?

He may have sprained it on something,,babies are clumsy..the vet will probably give him metacam for anti inflammation and pain. Hope he's ok

I hope he'll make a full recovery. Let us know how the vet visit goes!

Poor little dude. If you can, pad his cage so that if he falls, it won't hurt him. Put in lots of flat perches so he can rest his other foot.

Hope all will be OK. Good that you are taking him to the vet.
