Once properly hydrated I would give her Safeguard paste at 0.23ml per pound orally for five days, but I would only do this if I knew she was properly hydrated. The 60ml syringe is what I use and I would start by giving her 10ml per pound of gatorade or pedialyte now, then again in 60-90 minutes and one more time in a few hours as long as her crop was clearing.
How do you suggest tube feeding K? When have to do anything with my geese or ducks I get them from behind and straddle them this keeps wings against their body so they don't interfere. But I've never had to tube feed any one.
