My dog is raw fed. Barf as she sometimes has rice or veg although her main diet is raw meat. You want to aim for 10% bone, 10% offal and 80% meat over a week . I havent taken that step yet but if I had to process spare roosters I would have no problems skinning and feeding it to her. I would personally skin although I know raw feeders who dont. My reasoning behind this is that my dog has little to no prey drive (she has to be discouraged from licking the guinea pigs and cats neither of which approve of slobbery kisses) and I would rather she didnt associate my living quail with the meat.
A dog who isnt raw fed needs a gradual introduction and never feed dry kibble and raw the same day as they digest at different rates. All new meats may upset your dogs tummy at first, they suggest sticking to chicken for the first week as an easily digestible white meat and if that goes down ok then introduce a new meat (ie quail) the next. The other thing to watch is that your dog chews rather than gulps at first- sometimes its so new and good smelling they try and swallow it without chewing so they suggest at first holding a chicken wing for example so they are forced to crunch bits off. Once they get the idea its not a problem. Wont bore you with more, but I find my Nutmeg has a nicer coat and rarely has upset tums than with dry. Also one poop rather than 4-5 a day!!
