My own interpretation -
I watched HM pull a tidbit off the fish and then sit and hold it waiting for DH2 to chomp at it. DH2 just stayed put, didn't know next step was theirs. HM would watch as the juice dripped off the bit and finally swallow the rest. Then she'd pull off another bit. Happened quite a few times before everything got in sync.
Ain't easy being a baby eaglet!
This could take a while. Plus - we still have to fledge 6 gooselets, aka goselings.
