Egg Size

[Cesar Villegas]

Hi everyone I was wondering if egg size decreasing has to do with genetics, environmental or diet? One of my pullets started laying a nice large egg, now she lays a borderline medium.

Well according to this Canadian site, and other sites agreed, the hens weight and diet has the most to do with size Cesar.

• Hen body weight is the key to increased egg size. Bigger hens produce larger eggs than smaller hens and bigger breeders produce larger eggs than smaller breeders. For modern White Leghorns, rearing pullets that weigh at least 1.35 kg (3.0 lbs.) at the start of egg production will increase both hen weight and egg size.
• Protein level in the feed can be used to alter egg size at different stages of production. In the first couple of months of egg production feeding a high, 18% to 20% protein layer ration will increase egg size. After the flock has reached maximum egg production, high protein diets no longer promote large increases in egg size. After 36 weeks of age, feeding rations with 15% to 17% protein will help to slow increases in egg size
