I would just take a quick look on the bag of the pullet mix and make sure there is no "egg withholding" period mentioned. I only suggest this as the bag I was given had it on there, mind you the guy who sold it to me never mentioned anything about it and I have since checked the companies website and found there are 2 types of pullet feed, only one mentioned the egg withholding period. I had 1 hen laying eggs but couldn't use them as she had been eating the pullets food
