Breeding for higher egg production.
We get a good number of inquiries about egg laying and what breeders of Standard bred Rocks do about egg laying. I'll share a little bit about what I do and perhaps others can share what, if anything, they stress in the breeding goals.
Our Plymouth Rock varieties, Barred and White, will never lay like the Mediterranean breeds do, as they are simply too large and too focused to balance egg laying with meat production. But 200 eggs a pullet year is certainly respectable egg production and well within the capabilities of the Plymouth Rock. So how do we include egg laying in our breeder selection process?
My chosen breeders were selected last fall and I took them to the Knoxville National for judging. They passed with flying colors. Since then, they've been in lay and I've had a 90 day period to judge them for egg laying before including them in the breeding pens in a few weeks now.
1. How many eggs are they laying? To determine this, my layer groups are small. 4 pullets. I quickly learn which egg each pullet is laying. It's not that difficult. I also must collect eggs three times a day in winter to prevent eggsicles and I notice who is "in the box" and who isn't. Soon, I'm pretty sure about most of them. 4 eggs per week. 5 eggs per week. Only 2 eggs per week.
But, sometimes I semi-isolate a pullet with a pen within the pen, so as not to disrupt things too much and check an individual pullet or hen's laying. This is as close to trap nesting as I can do. It works for me. Most of the time my suspicions are confirmed.
2. I not only check egg laying rates, but I am also checking egg size and quality. Since I dislike hatching from medium to small eggs, if a female cannot lay at least a medium to large egg, with large being much preferred, I have second thoughts about including her in the breeding.
3. I also check interior egg quality. If a female continues to lay eggs with meat bits or specs of blood within the egg, I watch her closely. I keep checking those eggs. While not unusual for starting pullets to sort out these issues, it must not be allowed to continue.
So in conclusion, selecting breeders is not just about physical characteristics, not here, not on this farm. Do all breeders take these steps? In all honesty, it would seem quite doubtful. It is not a secret that some "lines" are notoriously poor layers, and layers of very subpar eggs. If egg laying isn't important to a breeder and the breeder puts the majority of focus upon the exhibitions, sooner or later, it is understandable that a strain defaults to being less than stellar layers of high quality eggs.
This topic might stir up a bit of a hornet's nest, but that's alright. It's cold. It's winter and a new topic won't hurt us.
