I have always assured my egg customers that they could never find a chick (or start of a chick) in my eggs because they are collected daily. I may have to stop saying that. I am not new to chickens, eggs, hatching, etc. I have been doing this for many years. I am a relatively intelligent person, but I am having a hard time figuring this one out.
I have been collecting eggs for hatching. I have a pen that I am particularly interested in raising chicks from, but of course, the hens in there are stingy with their eggs. I have been writing the dates on the eggs from that pen so that I can be sure to set them while they are fresh. I store them on the kitchen counter and tilt the carton several times a day. We keep it cool in our house and don't run the heat until it gets down to below 60 degrees. We turn on the AC if it hits 72.
I was getting a plastic bowl out of the overhead cabinet and one fell onto the tray of eggs, cracking one of those "important" eggs. It was marked 3/21 indicating that it was laid and collected that day. I marked it with a large "D" which is our sign for eggs that are okay to put in the dog's food. Thursday (3/27) my DH cracked the egg into the dog food and it contained a partially developed chick. It looked like the pics of three day old embryos except that the yolk was more tan than yellow and was firm and the size of a marble. It had veins on the outside of the yolk and the albumen was watery. The embryo was two lobed, with eye spots on one lobe, and it was just a bit larger than two BB's.
I know it was not overlooked in the nest box, there is only one nest in that pen and it is eagerly checked daily. It did not get warm enough outside to develop while in the nest nor while waiting on the counter. I guess it is possible that a hen sat on it all day if it was laid early, then collected late, but it sat on the counter for several days at well below the necessary incubation temp.
Is it possible that the hen held the egg inside her body long enough for it to start developing before it was laid? Has anyone ever heard of this before? From my research, it looked to be at about three days old. I'm at a loss...........
