Set a dozen eggs on February 28th about 9:30 at night. Temp stayed between 99 and 102 degrees thoughout incubation. Was thinking 21 full days would be the 21st or 22nd. Took out turner on the 19th, added water and closed up the incubator. Yesterday, the 20th we had a chick hatch about 9:15 am. Had second hatch at 7:45 last night, and had one pip and zip about the same time, maybe a second one pip, then nothing. It has been over 24 hours and we have not seen anything. Now we have another chick just pip and started zipping. We have not been fussing and paying with the eggs, only took 2 out to candle and since they had dark brown shell cound not see anything so left them alone thinking the less handling the better. I have read the link for when to assist and it has stopped me from getting involved. When should we remove the two hatched chick? Is it normal for eggs to take several days between chick to hatch? Are the chick safe with a possible dead chick in the incubator? I had though we might only have a 1/3 hatch since it was our first time. I never knew I would hurt so bad thinking we killed the chicks. I have been close to tears tonight. Any advice would be helpful and appreciated.
