I have these two pekin duck eggs that are on day 14 of incubaton and i candled them today and found that although there are still veins in the egg, there seems to be a large bubble around the embreo and the bubble is growing and the veins are still there, and this is happening in both of my duck eggs! HELP!

Does this bubble mean that they are dead????
