If I had known my hubby was going to buy the incubator , the fan , the turner, I probably would have went with a slightly more expensive better reviewed incubator. However, I sent him to the store to get parts for a homemade incubator (which he was then expected to build). He went to
TSC instead of Lowe's but he did get me all the goodies such as the fan and the turner. We added a little portable temp humidity gage that shows now, high and low. Plus we kept the two manual temp gages that came with it.
My point being I'd probably thrown a little more money at it and bought the hovorbator or a
brinsea, but since I didn't I can tell you.
I've had success the my Little Giant. I thought I'd only use it one ever two years to hatch out replacement hens. However now I have hatch fever and I'm on my second hatch with more in the bator. I ran out this spring and bought just the LG unit for $40 and made it into a hatcher so that I have an incubator and a hatcher, still haven't spent that much because LG is cheap. There is a thread here dedicated to LG's where you can see the up, down and more importantly how to make it work relatively well.
My last hatch I had a very high hatch rate on the eggs that developed. I don't blame clear, infertile eggs on the bator nor do I blame the egg I dropped.
I started with 45 eggs I now have 33 in the hatcher which I feel pretty good about their chances of hatching. But out of the 12 not hatching 10 were from infertile completely clear on the candle at 14 days. Only 2 were quitters.
I have had very little trouble holding temp or humidity. I find if I incubate in my house in a room that we don't use, away from the window and not in front of the air conditioning vent. And if I keep the whole house thermostat on the same temp it works really well and is very stable. However if thing in the room change the LG has trouble 'perfectly' holding temp. Such as I didn't get the hatcher til about 3 days ago. When I plugged it in, in the same room. My incubator LG went up to about 102 (because the room was now hotter). I had to adjust it down. Adjusting an LG is tricky but can be done. But if you keep the room stable the LG is stable. I'll follow this up, Monday with my hatch rate from what is currently in the bator (shipped eggs).
