A friend of mine is having me bird sit her 4 chickens which she thought were 2 barred rock hen, 1 RIR hen and 1 RIR roo. They are young, just a couple months and haven't started laying yet. Right away I knew something was up because the RIR "hen" was crowing. I haven't seen much of this other in than in hens lacking a roo, which we definitely have. "She" has a pea comb, no spurs, and no definable roo tail, but this morning I watched her do the chicken mating dance and mount one of the barred rocks....so I'm thinking Auracana mix? Are there any other breeds that can look like a RIR but lack a tail?
