The one had shorter tail feathers that spread put a little like a fan. The ours are longer and go to a pointBee said:When they are really young, the rooster's tail feathers come in slower than the pullet's...they will be quite stubby, in fact. At the stage yours are in, it would be hard to tell any difference except from that fact..the shorter, stubbier tail....but later, if you have a rooster, you will start to see some differences in the hackle and saddle feathers, as well as the shape of the tail feathers, that will indicate the sex.
I was thinking the tail standing up was a pullet. Man if I have 4 cockerels ill die!Bee said:Stands like a little cockerel too! Only time will tell but you just might be onto something there...that's a good pic and certainly looks much like a cockerel. As time goes along, the differences will get a little more noticeable...soon.
