have a 7+ yo pekin duck that started lameness appx. 1 yr. ago on right leg and she's struggling a little more now. although she IS still eating,etc.. fine she just struggles to get around. discussed it with my son this a.m.(got lots of silly advice) and came up with a plan to shoot her when she can no longer ambulate. we made an in-ground small pool for her that she uses but she doesn't stay in it long so... just sad.
