We have a flock of 15--13 girls & 2 boys; they'll be a year old in mid-April. Eggs average 1.5 ounces each, with some edging up to almost 1.7 ounces. Feed store birds. I don't know which hatchery.
At one time, in late fall, 6 of the girls were broody. Currently 3 are. One has 4 chicks that started hatching last Friday. The last hatched today, though under the second broody since mama kept kicking the eggs out. (Staggered hatch due to the very, very cold weather & inexperience of the pullet, I think.) Another broody is "due" on Valentine's Day, 6 chicks. The third sits on air.
Another girl hatched out a mixed clutch (3 of our eggs & 3 standard eggs from our neighbor's flock) in mid-December.
Egg production has been down during the cold weather, but the coop is not heated nor do we supply extra light. Still, they provide us with more eggs than we can eat.
They've been a joy, an endless source of entertainment. And do those eggs tastes good!
Although we have a mixed batch of babies coming in a few weeks (BOs, Americaunas & BRs, all bantams), wouldn't hesitate to recommend RIRs.
