Its best to give kits plenty of fresh meat and lots of variety, after a few months old if they havnt tatsed it they dont always know its food, kits have huge appetites and will tackle anything.
I find ferrets fed on meat diets so long as its varied are chunkier and have nicer coats and cleaner teeth.
All meat should be fed raw, ferrets have a very short digestive tract hence the frequent pooping, it means they are able to eat raw meat as any bacteria is dispelled quickly before it can do harm.
its important to vary the meat, whole carcass food id best i.e rabbit pigeon etc they can also have chicken wings but you may need to cut it into sections or they stash a full wing, these clean thei teeth, also chicken thigh/ breast. Day old chicks but no more than one a week as they dont contain any real nutrition but the feathers help to clear the digestive tract, these also seem to be one of their favourite foods.
fish fillets, i get the cheap frozen ones from asda and cut them up, tuna, sprats, pilchards. sardines in oil or tomato sauce but drain the oil first.
raw egg mixed with cat milk, soya milk or lacot free milk oh and goats milk is fine but not cows milk.
mince, the cheapest is best for them, heart and kidney, tongue etc some people say dont feed pork and others say its fine, stay away from bacon and processed foods like ham/sausages.
in time of sickness or when your ferrets need a bit of weigth gain use chicken complan from the chemsit but make sure its chicken as the other flavours contain lactose or chicken baby food, these can also be fed as treats.
Anything else feel free to ask
