The amount one tubes depends on the bird's size and how well it can tolerate feedings. I have a RIR hen that I can stuff 180ml into twice a day, but she's used to being tubed, so her crop can handle it. Please don't try this, this is way more than most can handle!
A basic guideline for amount is 30ml per kilogram every 6-8 hours, but what I would do if I were you is give the 30ml, then check her crop. Can you feel food in it? Is there a slight bulge or a big bulge. If there is a slight bulge, try adding another 15 and keep doing that until there is a moderate bulge. If you can feel food in the esophagus, that's too much.
I don't explain things very well, so be patient with me, lol, and ask if I've written something that's not crystal clear.
