I have 2 Buff Orpingtons and 2 Lavender Orpingtons. One lav looks to be a roo. The other is smaller but has a comb and wattle but I inderstand even the hens can have wattles. Now I want to identify by their tails. Pullets have fan tails, roos have jagged tails. That's what I was told. I'd love to see some pics demonstrating this. Any help?
