Nickel Chloride

Feb 2018
Hello to everybody! This is my first post here and I really need someone to help me.
I am going to perform an experiment by injecting nickel chloride to chicken eggs.
I'm gonna use physiological saline (0.9%) to dissolve the NiCl2.
I will inject 0.1 ml of the solution NiCl2-saline to my eggs.
The doses of NiCl2 are ranging from 0.005 mg/egg to 50 mg/egg.
My problem here is that I don't know how to make it.

For example, I have 6 eggs and I want to inject the 0.1 ml of my solution from my first dose of 0.005mg/egg. How much NiCl2 and how much saline do I need for making the solution?
