What day are they due to hatch? If they are due Fri, they would be OK till Monday, some will hatch late, maybe Sat or Sun, so that gives you a few days of them being OK in the incubator. I like to get mine out daily, but you don't have to. If you have your brooder area set up with the heat lamp, food and water, maybe your Grama could check them and take the hatched ones out and move them to the brooder every day. You need the brooder to be about 90 dregrees for the first few days, but have an area that they can move away from the heat if they get too warm. The first few that go into the brooder will need to have their beeks dipped into the water, but after that they will show the other chicks what to do as more go into the brooder.I like to dip all their beeks, but again you don't have to. They don't eat alot the first few days, so if you have a couple of pans of food they should be OK.We leave Friday the 27 and get back LIKE Tuesday or Wednesday
