thanks,
going by these calcs they eat 120g X 365 = 43.8kg of feed per year, so the question would be how many marketable eggs do they produce per year. Bit hard to work out cause I dont know the production period. If the ratio really is 11:1, that would mean 43800 / 11 / 61 = 65.2 eggs.
From the jist of what you saying it sounds like they produce more eggs than that, so the grain efficiecy ratio would be a lot better.
