Took a pack of chicken thighs out freezer yesterday AM to put into slow cooker this morning for tea tonight. Checked them just and still a few bits of ice on the chicken so not thoroughly done. Put them on worktop hoping they will defrost quicker so I can bung them in about 11. I’m out after that and want it ready for when I get home so don’t wanna oven cook them later. Is room temp ok or should I do something else.
