How long does a hen stay fertile / How long to make Fertile eggs

post #1 of 15
Thread Starter 

Hi,

I currently have a mixed barnyard  flock consisting of several breeds.    I would like to separate out a few breeding sets in order to obtain purebred eggs.  How long do I have to wait to collect eggs once separated to guarantee purebred offspring?  How long does it take for the eggs to become fertile once separated with the right roo?

Any advice would be greatly appreciated.  Thanks:D

At least three weeks should do it, though on rare occasions, there have been cases of eggs fertile by one rooster up to a month. Most are safe by two and a half, but three is what I'd do.

A hen will normally stay fertile about two weeks after a mating.  Sometimes less, sometimes more.  Many breeders use three weeks before they assume the eggs are fertilized by the right rooster.  There have been reports on this forum of eggs being fertile about 3-1/2 weeks after a mating, rare but evidently it happens.  So three weeks and you are pretty sure, four weeks and you are real safe.

It normally takes an egg about 25 hours to make its way through the hen's internal egg laying factory.  It can only be fertilized in the first 15 minutes or so of that journey.  Assume a mating occurs on a Monday.  Monday's egg will not be fertile.  Tuesday's egg may or may not be fertile, depending on what time of day Monday the egg started its journey and what time the mating occurred.  If the mating occurred on a Monday, Wednesday's egg will almost certainly be fertile.

A rooster does not necessarily mate with every hen in the flock every day.  Notice I said after a mating, not after they are put together. 

Hope this helps.

To complicate things I read a post long ago, and of course I can't find it, that reports an interesting phenomenon.  When a hen is covered by a second roo, that too is the one to father all the chicks. The upshot of this post was that in 2-3 days of a hen being covered by a new roo, he's the daddy. I wish I could find the post; the source was pretty reliable as  I remember. THen my understanding is that if he's removed, she's likely to be fertile for 2-3 weeks. THe old posts make for great reading--just takes a bit of time but well worth it.

I use 2- no more than  3 weeks as to your answer on how long your eggs stay fertilized coming from the hen.  However, be sure and keep them in a cool place like 70 to no more than 80 degree room temperatature and incubate by 5 days otherwise the fertilization and birthrate RAPIDLY goes down AFTER this time.  Best of luck building up your pure bred flock.  wink.pngroll.png  TheRealMadDog Chicken Farmer

How long does it take for a chicken to cross a road.......depends on the chicken and several factors and if there are hens over there etc............... if he happens to be a rooster and is feeling amorous. wink.pngfrow.gifThe Real MadDog's Chicken Farm(ex USAF Fighter Pilot and US Airways Airline Captain(retired now and raising various breeds of chickens/chicks).

 I think what the statement meant was the idea that if a new roo is introduced and breeds the hen the younger sperm, from 2nd roo,will more likely fertilize the egg but this isn't always the case. I would say 3 weeks is about what 75% of poultry material suggest for chickens.
