yes especially in the air cell when the baby starts breathingOk, question .... I've searched but couldn't find the answer.... 3/4 of my goose eggs are a couple days over due, I wasn't to worried knowing they may not hatch on day 28.... candled this morning and can see them this morning and 3 of the eggs look really good, air cell has dipped nicely and they rock overtime I whistle lol... candled tonight and two of the air cells dipped even more, can see a shadow in the air cell, very slight but a shadow... put them back and was just looking at the eggs with a flashlight and noticed those three eggs are not the bright pearly white they were, they are almost dull yellowish color... my question ( finally) do the eggs change color prior to hatching?
Did you help them? It's not often that they hatch themselves without absorbing the yolk. It does happen but is rare. Birds sometimes pip is odd places and can still hatch themselves. If the baby has an external pip do not be in a hurry to help. They can breath so you have time to let them do it themselves. If you temperature is 1 degree low it can add 2 to 3 days to the hatch date.What causes the gosling to pip early, but then still have the yolk out? My first 2 hatches went pretty well, but this third one is a disaster. The first 2 groups, hatched on the 28th day as well as this last one, but every chick has the yolk still out...I've followed the advice about wrapping in a wet paper towel, etc. One of them pipped in the side of the egg not in the air cell, I caught it before it drowned. I saved one, lost one, and am now working on the 3rd. 3 other eggs have not done anything yet.
