It's fine to let them on the field as long as it is well frozen; only problem is if it is thawed and muddy and they churn it all up with their hooves.
There are both advantages and disadvantages of spreading manure in the late fall or winter. It's easier to get out there when the ground is frozen, and you're not setting back the active growth of grass. OTOH you are losing a bunch of the nitrogen content that way (to the air, and to runoff) and it is definitely a no-no if your land drains to a stream or lake or other living watercourse, because winter manure spreading creates a lot of nutrient loss into the watercourse and resulting eutrophication and summertime explosion of lotsa algae that kills a buncha aquatic things.
(The above only really applies to fairly fresh manure. If it's been composted for most of a year, or less if you've been actively managing it with a tractor and thermometer to get good hot fast composting, there is not much problem with nutrient loss or runoff)
