We keep four of a cross called Black Rock and the birds have been in
lay for about three months or more now. Excellent eggs and quite often
we will get huge ones with double yolks.
Never see these in commercial pack so I assume they get sorted out.
However, what causes the souble yolks? Is it something over which you
can exert an influence if you wanted double yolks?
Thanks |

Its not desirable in the commercial world as it strains the birds and
halves
the potential number of eggs you will get from the individual
Its not common in Black Rocks but you obviously have one bird with the
tendancy to pick up two ova as she starts her egg making
We used to keep a commercial hybrid Warren X Studler (unrestricted
free range, optimum conditions, excercise and feed; no artificial light
or heat in their night hut). Particularly sturdy hens would often
produce a lot of double yolkers in their first lay, and even triples.
When they started their second lay season the doubles rapidly decreased
and older hens just produced single yolkers. We still got a phenomenal
number of eggs per bird, and they usually laid all through their first
winter . Of course, a hen can't keep that up long and they had a short
natural life span (3 yrs if they were lucky ) compared to the 10 years
I've known in old-fashioned breeds.
The first sign they were about to turn up their toes, was eggs with no
yolk at all; and/or eggs enclosed in a membrane but no shell.
In around 20 years, I only once had a hen which prolapsed. So,
although double yolkers may be a strain on hens living in commercial
conditions, it doesn't seem to have a negative effect on the health of
commercial hens which are living the life of Reilly in the old
fashioned natural way.

Obviously we tend to hear about problems [with all types and breeds] rather
than "no problem" but certainly over the past years problems with double
yolkers in domestic situations [as that is who we deal with] have cropped up
enough to be noticeable.
Glad you did not have any issues.

Why would people who have chooks in domestic situations see double
yolkers as being a "problem"? |

partial prolapses; eggs cracking inside; fewer eggs
and such like
Its not the double yolked egg that is the problem but that some hens
laying
them are observed to have problems
OK, I'm with you now. I was wondering if the world as I knew it had
suddenly gone crazy. Double yolkers were always a favourite amongst
the people that my parents supplied eggs to. A treat for children at
breakfast time but then that was back in the olden days when children
were still fed breakfast.
Hi, Farm1!
Breakfast? I guess my grandkids are special then; they still get hot
breakfast every morning before school, if they want. Their school
offers breakfast free, but most of my kids don't consider a roll or
pizza a decent breakfast. They get three squares from scratch here
when school is out, like the past two weeks of break. I have eight
grandkids here, five for breakfast each weekday.
I teach them to cook, and my 6-year-old grandson always asks for the
recipe of something he likes. He can then recite it weeks later. He
has a liking for eggs with onion, salt, and pepper. The toast has to
have garlic, though. YUK!
Double yolks are considered lucky.

As they should too. But too rare these days unfortunatley.

I was wriitng with my tongue in my cheek I've got to admit. And
partly because of the need for schools to actually offer breakfasts.
My daughter is a teacher and she tells me about some of the poor
little mites who don't get fed properly and breakfast in only one of
the meals missed.
But the school doesn't really offer pizza or rolls for breakfast does
it?

Gee that must be a handful. |
