Yes looks splayed, yes go to the vet. The quicker you can get him in, the better chance of success you have as Pixebeak said above.
The set up in the first picture is something that can cause or worsen splayed legs.
The bedding the bird sits in should be wood shavings (aspen, course pine will do if no aspen available).
Also, that appears to be a soft plushie? It is too big and should be removed as it is a danger. Find something smaller, if you don't have anything, a tied scrunchie or a rolled up kids sock will do.
