Eggs and milk aren't getting more expensive to produce. So, if the currently-cheapest brand increases its price, it's opening a window for new competition to sell at the old low price. It's possible that anticompetitive forces would prevent that competition from emerging in many cases, but I would not say that it is obvious that prices will increase under UBI.
