My bantam cochins are broody little girlies. They're only 9 months old, and two are on their second set of eggs already. The third is raising her first batch. I bought these girls to be my incubators, and they've sure proven themselves with me!
They lay very regularly when they're not broody. I was getting 3 eggs a day from the 3 girls before the broodiness started. These are from Ideal Poultry.
