It would seem a bird walked on the concrete while it was still wet. Wouldn't the concrete also have stuck to the bird's feet, hampering it?

Hypothetically yes.
Concrete has a very high PH, between 12 and 13, it can even test at almost 14, depending on admixtures , letting that sit on on skin can cause concrete burns.
Its less about how thick the skin is and more about the normal conditions the legs are in, and how resistant those legs are. Seabird legs are going to be adapted for a higher ph than humans, and probably be more resistant to a high ph than people, but a ph of 13 or 13.5 is dangerous to any living animal, except perhaps an extremophile
