I am still not sure what you are trying to prove or disprove. It is silly to think that eggs should be laid with a fully formed vascular system. This is not speculation. It is fact Jonny. They should not have a vascular system when deposited. The very reason for the vascular system is to collect oxygen. Why would that need to form while still inside the female. The thing is, I have comparisons while all you have is one thing you constantly see because you do not change methods. Your observation are fine but the conclusions you come to are pretty funny coming from someone who has only been breeding egg layers for 3 seasons. I have studied this topic in depth and applied it for years. Long before you even knew what a hognose was. Every single time a female is offered porper nesting and lays her eggs within 5 days of prelay, the eggs do not have a vascular system. When females are not offered proper nesting, the female takes far longer to lay and the eggs have a vascular system. There is a trend Jonny. I am also a bit skeptical of you supposed hatch rate. How are you getting your numbers? Anything documented to support your claims? I only ask because everyone claims to have the same hatch rate and it is complete BS in most cases. Not saying that you are BS-ing, just that I have heard the same claim hundreds of times. Also, how many hatchlings are produced that never take off? Not trying to be a jerk, just put your money where your mouth is.
