I had to move my broody hen out of the pen with the other hens because they were getting in the nest with her and adding more eggs. She started out on 17 on Tuesday the 19 but ended up with 22 on Wednesday the 20. Anyways, when I moved her, I did it at night and she was on the nest when I went to bed but she was not on it when I got up and hasn't gotten back on after a couple hours. I brought the eggs in the house but I don't have an incubator. I have been reading the homemade incubator pages but I don't have any thermometers or hygrometers. I have water,lightbulbs, heatlamps and cardboard boxes, and plastic tubs. Can anyone tell me if it is possible to save the batch and if so can I make it without thermometers and so on?
