Slow cooker Turkey crown

[Sundaychiller]

If anyone has used this method, can you please help.
Recipes online are saying 5 hrs on high then other ones are saying 5hrs on low which is correct?
Do you put stock in the bottom or not? again conflicting recipes!
Thanks for any help

We tend to do a whole chicken on low for 5-6 hours so for a turkey crown, I’d think it’s more dense, so longer on low, or about that on high.
On a bed of carrots and onions just to raise it off the bottom, and some water, which is used to make the gravy after it comes out.

Thanks for your help.
Has anyone done a turkey, who can help too please?
