I kept the eggs at room temperature for about 3 days before getting them to the hen to sit on.
Possible, yes, realistically, the probability is low. I would candle them to see if there is any life or internal pips. If they haven't even internally pipped, I wouldn't count on them hatching. The farther you get from day 21 the less chance of hatching and the higher chance of developmental issues if they do. I personally could never throw out an egg that still showed signs of life, many people do by day 23 because the chances for healthy chicks are significantly smaller.
