Hello all! I'm a first time hen. I collected fertile chicken eggs from a friend's farm and yesterday (Sun, Feb. 9) was the expected hatch date. I've had problems keeping my temperature up though, so I'm expecting they may hatch a bit later. I've seen in previous threads that some clutches hatch as late as day 25. I haven't seen a thread with my particular problem, so I decided to post my own. Now, I have a homemade incubator (for now) and it's worked well so far, aside from the occasional temperature drop (not too much of a drop though and not for too long). I candled my eggs a bit late, day 10, and removed the infertile/non-developed eggs. I candled them on day 17 and saw they were still growing and almost entirely filled the shell. On day 18, they went into lockdown. On day 21, I checked on my eggs fairly often. I noticed one of the eggs had turned over about a quarter turn, and I got really excited! No pipping yet though. I went to bed last night (day 21) before my husband. Before coming to bed, and unbeknownst to me, he turned the light back on in my incubator (he meant well--he thought I forgot to turn it on before bed; he forgot I had a timer for it). --(I have my light set on a timer, which I've manipulated and tested enough until it turns off and on at just the right times to keep the incubator at a steady 100.5 degres Fahrenheit. I have the temperature higher because I have a still-air incubator and read it can/should be a couple degrees higher.)-- Somehow, my timer got all messed up and the light ended up staying on for about 8 hours. I'm not sure how long it took to climb in temperature, but by the time I got to it, the temperature was 114 degrees Fahrenheit!!! I have mostly resigned myself to the fact that they did not survive this temperature spike, but I wonder if anyone else has a differing opinion or perhaps personal experience with a temperature spike this high and for what I can only assume was less than 8 hours, since the temperature needed time to climb that high. Someone's comment on a previous thread was, "if hatching eggs was easy, everyone would do it." That makes me feel better... But the fear that I fried my chicks makes me feel worse again.
