Well, if your simply looking for egg production you can't beat a white leghorn. Some people say they don't like them because they say they are too scitish but lets face it.... any chicken can be scitish. I have 16 different breeds in my coop and the white leghorn is hands down the best layer. My flock started laying the end of september and my white leghorn has given me an egg every day except for 3 since then. That includes two double yolkers too. After her i'd have to say my speckeled sussex is the next best. My RIR just started laying so I'm not sure how she will be, but white leghorn and RIR and the two breeds used most by commercial egg producers.
