So this is my first time incubating. I bought 12 eggs from a local farmer who claimed these were fertile and i was sure to tell her that I was going to incubate them so that she knew i wasn't just going to eat them. So today ( day 5 ) i try to candle them, the shell was brittle and it broke. I felt bad because it had blood it it but it didn't look like it was developing so its not too bad. So I candle the rest and it doesn't look like any of them are developing besides one. I keep thinking that maybe its to early to tell or that my candling device ( my desk lamp with a piece of cardboard around it to funnel the light ) is a piece of crap because i can't clearly see through the egg. All i'm seeing is a bunch of dots and the airsac. I'm getting fraustrated and i don't know what i should do. Please advise me. Thank you.
