Give the split peas a good rinse in a colander, then place all ingredients into the slow cooker.
When you add in the ham bone make sure to nestle it into the middle of the soup in the slow cooker, making sure that it is fully or mostly submerged into the chicken stock.
Cook on low for 6-8 hours or on high for 4-6 hours. It will all depend on how fast your peas cook, they can be unreliable with the time it takes! I usually look at this as an all day, on low temperature crock pot split pea soup.
When the peas are soft and melt into the soup when stirred, remove the ham bone.
Cut off any excess ham that might be left and mix it into the soup.
Mix the soup until all of the green peas dissolve into the broth. Serve.
