age of a Turkey eggs development

[klilly20]

One of my turkeys laid a clutch of eggs I have been collecting them bringing them in the house to put in the fridge for some odd reason I decided to candle one it had movement and has air sack about 1/4 way down I put it in my incubator but do not know the age of the egg any suggestions?

Hard to determine the age, it takes 28 days for the egg to hatch. Can you see the embryo? Is it fully developed, the inside looks dark or just a mass that moves and you can see clear liquid? Can you post a picture?
