Add marmalade, lime juice, sauce, garlic and salt to a bowl and mix until smooth.
Add chicken and 1/2 the sauce to the slow cooker and toss until coated.
Cook for 2 hrs on low and then turn wings over and coat with 1/2 of the left over sauce. (At this point you may want to drain the excess liquid from the slow cooker. Optional)
Cook for another 1 & 1/2 hrs on low.
Remove wings from slow cooker and place them on a greased baking tray, coating in the last of the sauce. Cook in hot oven until brown and starting to crisp.
Remove from oven once browned and serve.
* Adjust the sauce to suit your pallet. Add more for a hotter sauce.
