I have two red sex links that have each laid an extra-large brown egg every day since they first started laying. It is my understanding though that their rate of lay will decline over time, so I'm waiting to see. I would recommend the cross breeds that are bred specifically for egg laying such as the Red Stars, Cinnamon Queens, etc.
For the records, my Australorp at 1 1/2 y.o. lays about 3 a week, my 6 m.o. Wyandotte lays about 4-5 per week and my (4) Plymouth Rocks each lay small cream eggs every day. My (5) barnyard mutts (daughters to the Australorp) give me 4 - 5 small cream/light brown eggs a day.
My Buff Orpington's lay a large light brown egg about 5-6 a week from each.
Hope this helps.
