Chicken doesn't have much smell, if any. So some new to raw dogs don't recognize it as food. I don't give chicken legs. Toooooo big. But since you have them, you can let her chew on the ends which are more cartilage. Don't let her have the long bone in the middle, but she could consume the ends. You'll probably have to sear it at first in a sizzling hot pan with a bit of butter or olive oil. Just a few seconds. Or cut it up into tiny pieces and sprinkle with parmesan cheese. I wouldn't do the skin right at first. Let her have a few bits of meat and then let her chew on the bone while in your lap with you holding it. Then you can control how much she gets.
I prefer starting new raw dogs off on cornish hens. I think they are easiest. One is 16 ounces, so whacking it up into 8 pieces gives you 8 pieces that are 2 ounces each. This is a meal. Since Amberleah is quite small, you might just be giving one ounce at a time. One ounce is about the size of an ice cube or about a tablespoon. Not much at all. It's very easy to overfeed raw and then you get loose stools. So just go slow.

If your husband is really not on board with raw, you might want to stick with a pre-made like Stella and Chewy's or ZiwiPeak. Both are excellent. Both are like real food (not hunks of raw meat). Once she is on those, you could slowly start adding in some raw. I don't like the idea of trying to hide it from him. Seems like that could backfire.
