So my 6 RiR are now in week 3... they have wings, and are starting tail features. See 3 of them here: http://picasaweb.google.com/jalundgren/BabyChicks/photo#5187295225079423618 It was a straight run. I've noticed that 5 of the 6 have tail features starting.. the other 1, bearly so.. so I'm hoping I've got 5 hens, one roo.. we'll see. I've noticed that they like to jump and try to fly (infact they kind of do), they can even get off the ground. The regularly 'play' with each other, flying into each other, trying to one up each other.. a lot of what I'd consider youthful behavior I think. They even face off each other off. I'm hoping this 'contention' is typical of pullets too, is not a sign I've got a bunch of roos. Comments?
