For boney meals Honey gets either Chicken Wings, lamb ribs/spine or pork ribs... she gets rabbit as and when I can get hold of it, and I have just found a source of chicken carcasses, so she'll get some of that too! As far as how many, it depends how big they are!! Honey normally gets 2 chicken wings, and I aim for about 150g for other boney meals (give or take, depending on what I've got) - once you are used to it, you really don't need to weigh, as you have a decent idea as to the portion size. I used to give her ox-tail, but she kept getting the larger peices stuck on the roof of her mouth, while she swallowed the smaller peices whole, so I gave up on that (likewise with Lamb neck bones).
Chicken wings are definately her favourite and go in a few seconds... others get carried around a little bit before she decides that she will eat them after all!
