Hi everyone !
I am new to here and need some duck help I have a 3 year old mixed breed ( ? Mallard mix) and she has been having this bright green very watery poop!
Last week I had her to the vet for calcium shots as she had been laying eggs and was starting to feel the effects of losing calcium in the process. she seemed to come around and then she started having this poop and gradually losing her appetite to the point where she has barely ate anything but is drinking! Can someone give me any ideas as to what can be wrong and what I can do !
Much appreciated

I would try to post on the duck thread as well. Just go to the top of this page and click on
Forum, then drop down to Other Backyard Poultry, and click on ducks.
