I had 3 ducks all about 2.5 years old. 1 male pekin, 1 female pekin, and 1 runner. The male became ill last wednesday and expired thursday early morning while in isolated observation. The 2 females are now just hiding in their coop and when I coax them out they will shortly run back to the safety of their coop. Do I just need to give them time? I'm lost on what to do for them. We lost a female runner 1.5 years ago to drowning and their behavior did not noticeably change at the time. Thank you for your advice.
