I'm still not sure I understand what you actually have in mind.
Rabbit droppings would make a perfectly fine manure if you had some way of gathering them in vast quantities, you're definitely better off just buying some compost or finding the manure of larger herbivores. Not a great idea to trespass on farmland but if there's a stables anywhere near you, the horses will regularly shit on the road and you can gather it up with a bag for free.
Most brambles are very hardy, you'll have noticed they tend to grow all over the place wild, but in their case
>Seed often does not germinate until the second year after shedding. Seeds have a hard seed coat and a chilling requirement to overcome. Plants take three years to flower from seed.
you're not going to get blackberries by next year. Unless you wait until spring and buy a young one. You could buy two and give one rabbit manure to see if it makes any difference to the growth if you're that keen on experimenting.
Don't play about with fox shit though, even if you were to sterilise it, it would smell fucking awful all the time.
