I don't know their exact date they should hatch. At the latest it would be the 20th,,4 days from now,,but I am not sure. I noticed 2 days ago ,,they are trying to break shell,,there are some small cracks,,looks from the inside out,,where the shell is broke. I candled them and can see them moving around,,,can't hear anything from them,,,but its noisy in the coop. What should I do??? The shells are very strong or should I say healthy!! lol Should I help break the shell??? Or will they work it out??
