I don't know what to tell you besides what I have posted above. I never had any trouble with my dog not wanting to eat the raw chicken. But each dog is different.
They are your dogs and you know them best. It's up to you if you want to put them back on kibble for a bit and then try again. I'd still think starting with some pre-made raw might help. Maybe they are just having a hard time adjusting.
And Jack has a good point too in that what you are feeding is not a complete balanced diet. Maybe do some more reading and change it up a bit.
I don't think a vet visit will help much unless they are really sick. Most vets are against raw feeding.
Good luck and keep us posted....
