Today, two years since our first crow, Marusia, appeared in our shelter. Before that, we had only storks, wild ducks and pigeons. Marusia suffered a lot: she had a broken wing and upper part of her beak, in addition she was very limp.
We do not know what happened to her, but I do not exclude that the nature of Marusia itself was the cause of the trouble. After recovering a little, she began to behave badly. Fortunately, gradually she became accustomed to life in the shelter and learns new crows rules of conduct.
