It all depends....
As MB stated, if things are blooming, then probably not. If you are getting your packages way to soon to fit this scenario, like some of the package producers are this year, you better have the feed ready.
Last year, I sold to a few new beekeepers who had lost there hives after installing packages in early April on foundation. They got sucked into thinking "the earlier, the better".
One package provider this year in Pa. is advertising packages on March 28th. I hope the snow will be gone for those unfortunate new people this year that was sold this idea is a good thing.
