Go with what Leyla says, she has dealt with more crop issues than I have.
You can try a bigger syringe, but if you are going to try to get it directly in the crop, then the 1ml is smallest and easiest to use (at least for me).
The Dulcolax (stimulant free) comes in like a gel cap. You can squeeze it out if you wish. I usually just put it in the beak and the birds swallows it

As you're finding out - all of us do things differently, soooo....it's really up to you to find what "works" best for your situation.
