I am new. I made a split with hopefully the queen and young bees and forgot to even think about pollen. It has been about four or five days before I saw any flying at the entrance at all. I believe with serup alone, that it will be ok till the bees get some forager age bees promoted. In my case they still also have to build comb. I am not yet even sure the queen is in the split or if she got lost in the transfer, I had wind that day and it blew an inner cover over with a fair clump of bees on it.
I think it will be ok and I am waiting for about ten days or so and I will look for proof of the queen laying, If she is, fine and if not, I will add a frame of open brood. I do believe they would do better and do it faster with some decent stores but believe it will be ok just from feeding. I do not know how long it takes for workers to turn laying.
I am new so take what I say as what I am trying and not as advice.
I hope this helps you in some way.
