Hello, we found a White Pekin duck at a pond across our street, and she seems to be injured, she leans to her left. And we have 1 pekin duck we raised with 6 chicks and they get along fine since St. Patrick's Day. Is it okay to introduce the wild duck to our white pekin and chicks? And how would i introduce them. Isn't it illegal to set free a domestic duck? Please HELP!!!! And how do I help her with her injured joint.
