I bought 6 eggs from a farmer on Craigslist, and he shipped them to me on the 27th of Feb. I got them at my front door on March 1st. Immediately put them in the incubator. After a week, 4/6 developed veins, and were moving. Around week 2, the veins of one egg dissapeared completely, but no blood ring. Is it a goner? It's March 22nd, so they were supposed to hatch yesterday at the latest. No movement in the last 3. No blood ring, temps/humidity normal. If I candle them, there is the slightest hint of veins remaining. But not visible in one of the 3. The chick takes up nearly all the egg space now. No pipping either. Really really worried. This is my first batch. What should I do? I can try to take a photo is that helps? Although, it will be hard to see.
