correct, to make $, you need several hundred hens etc....
most of us do this, to not make $, but to have fresh eggs, maybe sell a few to friends and family.
I make enough off sales to just break even and buy another bag of feed.
I have 14 girls...in the peak summer months, I will get about 11 eggs a day...
Your estimates are a tad high...even on great laying days...not all chickens lay daily. I only have ONE girl who lays daily...my California White...a pretty medium white egg, every single day.
But the return in smiles and fun watching them...PRICELESS!
