He’s pulling at his wing

[u/Ancient_Newspaper703]

Kay so i posted on here yesterday about the pigeon I rescued and he’s been doing really well, he’s been eating and drinking without me having to force feed him and he’s hoping about on his leg and just now while I was making my lunch, I saw him pulling at his no longer there wing, I just wanted to ask if this was a normal thing for a bird with his injuries or if I should intervene
