Here in WI we can kind of
get away with that. If you spread it (not too thick though) about now while there's not much, if any, snow and leave it for a month or so until the soil is workable it won't burn your plants if you wait until Memorial Day to plant.
Just another note though, cow manure is best. The only reason I don't usually use fresh chicken or horse manure this time of year is neither of those animals actually fully digest what they eat. Be prepared to have weeds and/or "volunteer" plants of miscellaneous varieties growing wherever! We used to use the coop cleanings, stall cleanings, and duck pen scrapings on the garden each spring at the farm. There was always a LOT of hoeing involved afterwards to keep weeds and grass at bay.....
If you don't want to risk it, chuck it all in a compost pile for the summer and spread it out come fall.
