breeding/Fertility Question

[BREKEN]

Whether 1912 or 1939, isn’t it amazing how much we’ve learned since then? And with today’s media we can have a pretty clear graphic picture of what’s going on. I think this video really helps us understand much about what goes in with an egg inside a hen.

How an egg is made utube

For example, the oviduct does not contain six egg at one time. It takes about a day for an egg to make its way through the oviduct. If there were 6 eggs in there, the hen would lay 6 eggs in one day. The egg can only be fertilized in the first few minutes of its journey after it’s started its journey, so only one egg is fertilized at a time since there are not six in there.

Something else not mentioned there, but the heat inside a hen’s body causes an egg to start developing right after it is fertilized. That’s what causes the bull’s eye, the development of the embryo. If an egg were fertilized six days before it was laid, it would have six days of development when it was laid. Obviously that’s not the case.

I really enjoy reading history and geography books from that time frame too. Those old books are just fascinating to me. But I would not plan a travel agenda today based on that knowledge.

Thank you for the video!!!

Many thanks to Gurney for providing this link. Guess we are back to 2-3 weeks now. Broomhead's article was written before the discovery of the tubules.

I'd like to add that a few years ago, I got impatient, and tried for ten days. The new cock was infertile, and only one chick hatched. She was a mix from the previous cock. Forget about ten days, for sure! Mary
