I have a broody hen but no rooster. She constantly lays on the eggs that she and others have laid and I felt so bad taking the eggs from her. Discovered everyone's idea of buying fertilized chicken eggs at the grocery store, and after much calling around found them at Whole Foods in Bellevue,WA. Their Redmond store did not carry them, nor our local Trader Joes in Kirkland, WA. Their sell by date is Oct 4, so hopefully they aren't too old. When my little boys get home from school today we will place them under the broody hen together. We'll see what happens!
