Hello, I am new here, and am SO grateful for this site. Cheers to all of you! I'm actually a chicken owner, but have been fostering an amazing duck, Sherman! Watching him grow into himself has been incredible.. I was wondering if anyone knows about ducks mandible's? There appears to be a new kind of spot on the tip of his, just want to make sure it's nothing to worry about. Appreciate any thoughts, thank you!!
