Best foragers in my flock:
1. Light Brown Leghorn. She could live without layer feed and give me a big white egg laid in the bushes every day.
2. Light Partridge EE. not quite as good as the above and she'd still need supplemental feed cuz she's so tiny and lays such a large egg.
3. Cinnamon Queen, , BBL Polish, Pearl White Leghorn and CA White Leghorn. They are good too. and my BWA roo is good at helping to find food for his girls and calling them in to eat it and to ruffle feathers. :0)
4. Salmon Faverolle and Speckled Sussex and Barred Rock... these girls are equally good but they waste time doing dust baths when free ranging.
The rest of my girls are so/so... Delaware, various EEs, Ameraucanas, Maran, etc..
