Well, I ended up with only having 11 egg's that were from the batch of shipped egg's from Chicago so I marked them with a C" and then added one of mine marked with a "B" so that it would be an even dozen that went into my incubator at 9 am this morning. The batch of egg's from the other state will most likely be delivered tomorrow and any of those that are good enough to go into my incubator will be marked with a "M". All of them will be Bielefelder's , but I wanted to mark them anyway's so I can keep track of what hatches from where.
