Go get yourself a broody hen and let her do the work.
I had a 28 wk old Barred Rock that went broody back in August. She sat on that nest 24/7 and would only get up 1-2 times a day to go eat, drink, and BIG poo. I felt so bad for her because I kept taking the eggs others would lay in her nest because I don't have any roos for fertile eggs.
I brought home 6 possible eggs from the people I got my first goats from back in October. Candled them and put 4 of the best eggs under her. They all took and hatched out 1 black star (sex link) and 3 brown leghorns. She is the best momma ever. It is a joy to watch her raise her little ones.
I wouldn't want to do it any other way. I didn't have to worry about the temp or humidity or turning the eggs. My little momma did everything.
