can you take a picture of that? try not to worry to much...day 21 is too early to worry...you can always candle them to see what progress they are making so you won't be so anxiousMy second batch is doing crappyday 21 and I had 1 hatch, but it looks like it pulled its umbilical cord and its intestions are sticking out. A second on pipped this morning and unzipped halfway before dying. All the yolk was absorbed on it. There are 12 more in this batch and the last batch is on day 19 today.
