I have had 10 buff eggs in the incubator 4 days now. I candled them yesterday but I'm new at this and I'm not sure what I should be seeing in this short time. I can see a big blob on 1 side of each egg. it looks like a few of them have a smaller blob inside the big blob. Does that make sense? My temperature is always constant at 99.9 And I turned them at least 4 or 5 times a day. I just don't know what I should be seeing at this point. Any comments or help will be appreciated. I just don't want to spend my time incubating eggs that are not fertile
