I have been quite busy so I forgot to ask on this website but where can I ask questions regarding powder that I think could be a good supplement for ducks?Sorry for not updating, but yes it did recover. My duck has grown quite big now but I noticed it would occasionally still gape it's beak and quiver it but it's also because of our weather which is very hot. I also think my duck still has respiratory issues but not so bad like having fever. I'm just very happy it survived.
