i am sorry but none of mine do that I'm hand feeding 3 tiels right now just got done with 2 other tiels and I've hand fed a love bird and NONE have ever brought their food back up and ate it
its either it's getting into the lungs OR the bird is being over fed
and being showed one time isn't enough - at least for me it wasn't, I watched several videos over and over and over and then had my b/fs dad come over and show me and even know i've fed 6 so far - I am still not comfortable doing it, I'm scared the whole time But once i start i'm fine. it's just the starting out part each and every feeding.
