I recently took in a calll duck. I stupidly didn’t think about the three rescue ducks I have that are a mixed Muscovy and are sterile due to the mix. They are very large! I’m afraid to let the little call drake duck out of a pen because one of those sterile maybe hermaphrodite (?) ducks likes to mount the others who run from him/her. Can he/she hurt the little call drake? I can’t keep him penned up - he’s unhappy (call duck) so I’m wondering what to do. Thank you for your thoughts and advice!
