I have three Isa Brown Pullets that are laying machines. I like to keep records so that is what I did for the month of January. They laid a total of 93 eggs for the month.That is 3 eggs everyday. They were 27 weks old Jan1. Feed 31 lbs at .174 cents a lb.=$5.39 Replacement cost for 12 months lay = $1.00 Total cost $6.39 That comes to 82 cents per doz. Avg. wt. per doz. was 30 ozs I was schocked by the egg production . I had 3 eggs every morning at 8AM. It was very cold all month here in Michigan. Always below freezing. They were given water at 8AM and 3PM plus feed . I feed a 17% laying mash . The pullets cost me $7.00 each at 20 weeks and I think I will get $3.00 after they have laid out. I would like to get a calculation when I can pasture the hens and see what the cost would be. I'm thinking that it could cut the feed intake in half. Has anyone of you done that?
