It has een awhile since I posted. I use to hatch eggs yearly with a rather old sears & roebuck incubator. somewhere between 60 and 80 yrs old. 2 years ago it starting having little glitches every now and then so I stopped. I decided last week I would grab an incubator while at tractor supply. so I bought the little giant and egg turner. I have heard problems with them. But I figured with experience I could do it. Well I have a unit that fluctuates 4 degrees either way every day. It started off with 1 degree and keeps getting worse. I recommend not buying 1.
