Hey everyone I just rescued an adult Peking duck. I have no clue how to tell how old he/she is. And I was wondering what sex it is. My gut tells me a female due to lack of drake feather on her tail but maybe it's just laying down? Also need advise on how to get her to trust us. Anytime we go near her she lowers her body and starts huffing and almost hisses at us. And god forbid we get close she runs and frantically looks for a way out. We are keeping her in one of our larger brooder boxes while it's in quarantine. Any help would be great thanks!
