Depending on the eggs and your incubator Melholly, the hatch may be spread out over several days. The first out bumble about as well, disturbing other eggs and slowing them down. We use a red lamp on 24 hours for the first week and put them in a cardboard box. The problem you may have is someone burning themselves on the lamp because it has to be quite low to get sufficient temperature. The box needs to be high sided to prevent draughts and also have areas where the chicks can escape the heat. Very shallow drinkers with pebbles in to prevent drowning because chicks fall asleep instantly at any time. It will be 6 weeks before they can go without any heat.
