Thinking about flock size, 2014 egg production.
Current flock:
1 Ancona (white eggs)
3 Rhode Island Red (brown eggs)
4 Barred Rock (brown eggs)
2 Americauna (green eggs)
2 roosters (Columbian Wyandotte, Americauna)

Brown egg production 90/21 days or a bit over 4 a day
green egg production 30/21 days or a bit over 1 a day
white egg production 14/21 days or about 2/3 a day

7 brown layers - 4/day
2 green layers - 1.3/day
1 white layer - .67/day

add 2 brown layers, 2 green layers, 2 white layers depending on attrition. Buff Orpington (brown), 2 buttercups (white), 2 Americauna (green)... order in late September production starting in February. Current flock would all be over one year old...

2014 flock:
9 brown - 5.6/day
4 green - 2.8/day
3 white - 2/day
about 10 eggs per day from 16 hens.
