Ok so I just candles my eggs on their fourteenth day. About half of them havnt developed any since I checked them on the seventh day. I’ve kept my temp. At 99.5-100 degrees feghrenheit, and humidity is at around 40-50 percent. I use to keep it at around 30 percent till I read something about making it higher. I am using one of the styrofoam incubators from tractor supply that has the FFA stamp on it. These are eggs from my own birds. One had an obvious blood ring. The others are developing fine they are moving in the egg. What do y’all recommend?
