Weak grip on my conure and behavior change

by Chun
(Boston, MA)

About 3 months ago my conure have injured it's foot with a long nail. I brought it to the vet and he said it most likely pulled a muscle and prescribe some inflammtory meds for her.

Last week similar incident happened. It's limping on one feet. This went away for the past 2 days but both of it's feet is very weak. It could stand, jump on stuffs but with the need of it's beak.

I have changed to a bigger size perch for her. Would this cause it's feet to be like that? Also when she came to me, she always playful. But for the past 2 days, she came over and sleeps on my shoulder.

It's stool looks fine, but bigger then usual since the pellet diet. It was changed and adopted about a month to two months ago since the vet visit.

If anyone can give me some advice, it will be appreciated.

Thank You
