I have 5 week old Buff Orpingtons and Easter Eggers. I'm noticing a couple are starting to do what looks like challenging each other. They stand up really tall and stare at each other. One usually charges the other or chases the other away. Is this them just sorting out the "pecking order" or do I potentially have two Roos that are already having a go at each other? It's still too early, I think?, to tell the sex of them by looking at them though I suspect one (maybe two) to be roos based on behavior/stance/size etc. should I keep an eye on this or is this totally normal? Seemed to have started yesterday and has been going on and on since. No one has hurt the other.
