I had some chicks due to hatch yesterday, but to my horror I noticed that my incubator was 5 degrees too low yesterday morning, though it had been at the right temperature during the whole incubation when I checked. I adjusted it and it has been right on again since. I decided to check one of the eggs for signs of life thinking that my whole clutch may have gotten killed. I poked a hole in the end with the air pocket(I have done this in the past and the chicks usually still hatch without problem)and peeked inside. To my amazement I saw movement from a very underdeveloped chick. The membrane was still intact and there was lots of room for the tiny guy inside, it looked like a chick 4 or 5 days prior to hatching. I put him back in the incubator since I didn't damage anything vital inside. Now I wonder what I should do, leave them inside, if so how much longer should I give them, should I help them hatch, put them back on the turner or what? This hatch was a very important one and it would be terrible to lose all of them. I checked the calendar again and the date is the correct one, I have no idea what happened, the only time it was low was yesterday and this incubator has always been very reliable. I need to save these guys somehow!
