I have two 5 1/2 year old hens (Red and Black Sex-Link), five 3 1/2 -year-old Barred Rocks, and six 1 1/2 year old White Leghorns. I like to allow them to free range, but it's so hard to keep track of them all! The Sex-Links and Barred Rocks, are pretty easy, but the Leghorns are so hard. They split up individually and wander around in the woods and thicket. I've lost and found one once of twice, but I'm always so worried that I won't be able to find one. How can I keep them from wandering? Also, I'm planning on getting Buff Brahmas and Black Australorps, how is the ranging behavior of them?
