I now try not to even look at new additions for about a week so they can settle in. Sometimes even that is not enough. I have had some in the past feed the day I got them; however, I had one girl that took about 4 weeks to eat for me.
It is hard; however, patience pays off. Try once every 5 days, and have as little to no contact as possible in between.
I have never had to, so I have to defer when you should force feed to someone with more knowledge and experience.
