all my kids are chest bumping! my 4 month old runs at my three month old then bumps chests, then the three month olds crouches down and stays down. then my six week olds do it too! they go running at each other, bump chests but no one crouches down and they both walk away. they are all silkies. I'm pretty sure the 4 month old is female as she has a huge rounded crest on her head. the three month old I'm not sure of but praying it's a female! do the pullers bump chest with each other also? when I had my cockerel I noticed he more or less would spur. claws out Ward. they aren't doing this, but they are chest bumping. it got me worried. will a female do this type of behavior? it's a different type of sparing than my cockerel would do. like I said he would do this claws out.... but are females known to chest bump also?
