Thank you for replying! I got him two days ago, and I noticed it yesterday. I’m not sure of his exact age but I’m sure he’s two months or under. A picture wouldn’t help cause it’s not visual thing is more like his grip isn’t as good and I didn’t know if I should do anything to help him get
Most likely this is a foot sprain that occurred in the transition to a new home. These usually improve and resolve within a few days. If there is no improvement or worsening by tomorrow, definitely would want to consult an avian vet. Even with a sprain the birb should be eating and drinking normally. If this is not the case, vet care is also needed right away.
In the meantime, make sure food and water are easily accessible without having to climb. A fully weaned bird should not have weakness in any limbs.
