I had set 20 eggs, 16 made it to lockdown, 14 hatched. What is my hatch rate? 70% ? 87.5% ? Of the original 20, the four that had no development, were the ones that the thermometer was sitting on. Poor choice of placement on my part, but I have learned something, so not a waste. I had ordered black sex link eggs, and pullet eggs were sent. I had a great hatch with the pullet eggs, but I am curious. Three of them are obviously roos, black with the white spot on their head, one is solid black, a female. The others are black and smokey gray mixed, no obvious sex link characteristics. I guessing there is a mystery roo involved! (they look like Barred Rock babies) I am obviously pleased with the hatch of the pullet eggs, but..... what did I get?
