Unfortunately, the article doesn't say who did the study. But, thought I would pass along their results.
1. White Leghorn (no surprise there)
2. Black Sex Links
tied for second
3. Red/Gold/Buff Sex Links
4. Rhode Island Reds
5. Cuckoo Marans
6. Light Sussex
7. Barred Rock
8. Plymouth Rocks
The article went into a little more detail: While the Leghorn came out on top, it was only by 10 to 11 eggs over the Sex links. (The study was for one laying period, first lay, so young pullets. The RI Reds were 5 eggs down from the Sex-Links, and the rest were all equal with 3 eggs down from the RI Reds. The Leghorns took 12% less feed than the rest. The study was done on *all* egg-layer breeds, and meant to be a "top ten" but all other breeds fell so below the standard set by these eight, that they could not justify including them. Each breed was represented by a pen of 20 pullets, same weather conditions (pens inside a large building) exact same feed, (measured twice daily) hatched on same day, same water, lighting, etc.
The previous study was done in 2001, and the winners were the same with the exception of the Cuckoo Marans, which were not considered a "signifigant" breed at that time. That study went on for years apparently, and the finding remained the same through 3 laying periods, at which time it became spasmodic and unreliable (the egg laying, not the study.) The surprising result was that their Cochins (all known colors)although nowhere near the top ten in production, stayed in their full production for EIGHT laying cycles when their brooding tendencies were not permitted. They did not elaborate on how they managed to not "permit" brooding tendencies.
I found this quite interesting, and thought you would, too. I also found out that I have always WAY over-fed my hens, as they say that 20 hens should only be fed 4 cups of a complete layer ration daily. Water, oyster shell, grit and "garden greenery" were fed free choice. In extremely cold temperatures, they added 1 1/2 TEASPOONS of cracked corn per hen. If layer ration is fed in higher amounts, the hens become fat and unproductive, and become more apt to develop the habit of eating their eggs.
So can anyone tell me if the Cuckoo Marans have the beautiful dark dark eggs? I haven't placed my order yet, though I have to soon...
