Whole chicken is a little high in bone if you aren't adding another source of boneless meat. Start with catinfo.org, as recommended above, as there is a TON of information there. More than enough to get you started. If you follow her recipe, you could safely feed a balanced raw diet for the rest of your cat's life. Though as time goes on and you read and learn more you will probably end up making slight tweaks to better suit you and your cat.
Bones do not have to be edible sized if you are grinding them, but if you are not, you will have to find prey that contains small enough bones for your cat to eat. Edible bones can vary between cats as well. Some will be able to eat bigger bones than others, it just depends on their size and chewing ability. Ground bones will be easier for your cat to eat, as well as give you the ability to give small amounts of bone each day (which makes the risk of constipation or runny stools less likely).
