Re: [CHICKENS-101] fertilization?

 

Of course they can, and as the article explains that they can dump up to 80-85% of an unwanted rooster's sperm.  Hens have a little storage are that as we breeders have found out can last up to 3 weeks (sometimes a few eggs longer).  Three weeks is the standard to wait before collecting eggs hatching.

INFUNDIBULUM - yolk  with attached ovum is snatched up by the infundibulum.  It is at this point in the reproductive tract that the ovum is fertilized if the hen has been mated with a cockerel
 
When you read about sperm and  yolk development, the information given you, to me, explains why nutrition is so important for poultry. The sperm in the rooster are already dividing by meiosis and the hen's yolk takes over a week to form.
 
In the entire process animal protein, nutrients including trace minerals and vitamins are necessary for growth, development, and reproduction.  Laying eggs, even if unfertilized, is part of the reproductive cycle.  Our chickens are domestic animals, bred to need nutrients and calcium/minerals.  It's important to buy fresh made feed, have oyster shell on the side (you can't count on feed to always have the correct amount calcium/when it doesn't the calcium needed for egg shells comes from their bones) , poultry vitamins in their fresh clean water each day for times of stress (heavy laying, molting, cold/hot weather).

So are the hens storing the sperm and then the undeveloped eggs get fertilized as they become receptive? How many eggs can become fertile from a hens stored sperm? This is getting complicated! Can a hen store the sperm from more then one rooster?

Hens store sperm. Remember why we separate hens for breeding in mixed rooster for 3 weeks before we start collecting eggs?  Because hens can store sperm.  They can also dump sperm from roosters lower on the pecking order, et....

We have some friends who had alot of hens but suddenly got rid of their rooster. A week later, one of the hens started setting. She was setting on at least a dozen eggs from all the other hens, laid at various times. So far, 4 little chicks have hatched! 6 of the eggs were not fertile, and 6 were.  I wonder, too, how many eggs does a hen have on board at the same time, and are all the eggs fertilized when she mates, or are only certain ones, depending on their development? This would be good to know since one could 'rent out' their rooster from time to time and make him pay for himself! Hee!

I would want my rooster to breed my hen for at least 2-3 days.  Your hen can dump a rooster's sperm if she does not like him.  I would make sure his presence is accompanied by nutritious treats that will help egg fertility.  Can you put them in a garage or large pen in a basement?

OK, too early to be worried about this, but here goes.
I was wondering how often a hen needs to be serviced, or rather, how many eggs might be fertilized from a visit from the rooster.
Why you ask?  My town doesn't allow roosters, so I would have to board him out, but I can bring him for a visit when I want fertile eggs... but how often would I need to do this?
Seeing as I don't have chicks yet, it's a bit early to worry, but if he needs to be there before every egg, it won't be practical.
Thanks.
