Yep, it's official. I'm the worst hatcher ever! No matter how hard I try, I can't get one single chicken egg to hatch in my homemade incubator. It was really hot all last week and the bator spiked to 106*F. without me knowing, so I had to open the cover a little. The I had to go somewhere for the rest of the day and when I got back in the evening it had cooled down outside and temp. had changed to 96*F. I shut the cover all the way for the night. I woke up in the morning and it was at 101*F. Cracked the cover open so it wouldn't get too hot. It stayed around 99-100*F for the day. Outside temperature is warm so it's perfect. The next day it's colder than usual outside, so even with the cover shut and everything, the bator stays around 98*F. I'm SOOOO frustrated with this dumb incubator! It's a huge 100q Igloo ice chest and is suppose to keep temps. steady because it's insulated really well, but the outside temp. effects it a lot. And I can't sit next to it all day, adjusting the cover to keep it from getting to hot or too cool. So far we've had 1 single chick make it out alive in the bator(except the egg was incubated by a broody hen until around day 18 when she suddenly decided to not sit anymore and we moved the eggs into the bator). But we haven't had one single egg hatch after being incubated in the bator for the full 21 days. I just had 4 eggs in it the past 3 weeks that were developing fine. 1 was a small Bantam egg and is still in there and the other 3 have been in the bottom and are really late for hatching. Two of the 3 late ones were suppose to hatch last Monday(day 21) but haven't, and the other one was suppose to hatch before that. I was hoping for a good hatch because it's the last we were going to do for the year until next Spring, but now the results are disappointing and sad and we have no chicks, except for little Oreo who has been alone ever since she hatched. I'm just about ready to throw this bator in the dump and give up hatching for a while and let the broody hens do it, unless I find a for sale bator that is cheap(which will probably never happen). Sigh...I will find out if any of the 4 eggs are alive when I go to my dad's house today. Most likely I will find that all of them died just before hatching or while developing; it turns out like that every time anyway.
