This is new to me and is an amaing experience for my daughter and I. We have really tried hard to do our research. but have had a couple of errors. I don't think they are major but maybe. My husband set up our mini advance Brinsea for the first time for our six eggs. (received via organic poultry farm in our town) First question. Does setting the eggs in the incubator prior to it being ideal temp affect hatch day or hatch time? The eggs were placed in the incubator and then the brought up to temp. We read after the fact that the incubator should have been at temp and then the eggs placed. All six eggs were candled at first candling and one discarded. Did not develop. The remaining five have looked perfect all the way up to last candling on day 16. The eggs appeared almost full and all five had movement inside. The air pockets on all five looked to be perfect size. Today marks day 21 and as instructed on day 19 the turning wheel stopped and was removed. The non slip pad in place and water bin filled in the center. We have not touched or moved the eggs nor lifted the lid since. Second question. Today the Brinsea turned to a zero 0 at 11:00 am... That means day 21. So far no pipping. Nothing. I am worried that initially placing the eggs in the machine before it was full temp might have delayed the hatch.. When should I worry? Sorry so long I am just a worrier. My husband also set the eggs to turn every 45 minutes 1/4 turn and we hope that isn't a problem even thought the egg development looked on target as per candling. Any advice you have would be so appreciated. My father has chickens on his farm and these babies will join the gang if we do well.
