Forum:Coop feeding limit?

Hey everyone, lately Farmville wont allow me to feed neighbors coops. After I fertilize it never goes over to the coop or give me the feed bag icon. Is there some secret limit to how many coops I can feed in a day? I have searched forever and cannot find it. Zygna support forums just directed me to the neighbor problem thread but that didnt help at all ><.

Thanks for your time
