Our class has a R-com Mini with 3 duck eggs in it. They are on day 22 and are due on Wed 28th of next week. The teacher is afraid they may hatch over the weekend and want me to bring them home with me tomorrow. What are the chances they would hatch early? I set them on Sept. 30th at 11:00am. The first whole day would have been Oct 1st. I have a adapter for the car that I can plug them into if I had to take them home. I only live about 10" from school. We are in Florida. I candled them today and most of the 3 shells are dark inside except for an airsac. It looked like there were some veins in them. Not sure. One was moving around. The incubator is so small I put a couple of we cotton balls in it to try and increase the humidity. I can't get a get humidity reading because of the size of the incubator. The temp has been constant at 37. Please advise on what would be the best thing to do. No one even the teacher can get into the school on the weekend.
