Okay so I'm a first timer as far as incubating chicken eggs so I filled my incubator a lg still air that I installed a PC fan in and I'm hand turning just candled eggs for day 7 with my daughter and wow everyone of the 47 eggs are growing have embryos with little black eyes and move around like fruit in jello so cute I'm so ready for hatch day even if none of the chicks hatch at this point just seeing my 13 yo daughter away from her laptop and cell phone made this the best 40 bucks ever spent
