Crowing
*big sigh* yeah. I know. I didn't know roosters did passive aggressive but that's how its been...was just outside with my daughter, he didn't even look at her but there was lots of body language for me
Kleonpatra ... just opening up a conversation here.
I am by no means anywhere NEAR expert with chickens ... but I do know about animal ( entires ) behaviour. .... and there's not much difference across all species, when it comes to competitiveness, or protection in order to procreate.
I gather from your remarks, that your roo is or has been, in with one particular black hen ?? re : ( " i adore my one black chookie and I'd love to see her surrounded by fuzzy butts." ) If she has been squatting for you ( any time for you or any of your children - who must be kept away from rooster ) .... then he would see that as a HUGE challenge, to his [ incoming ] maturity to cover / mount. I know the entire male of any species is very aggressive when 'on the scent' - in order to pass on HIS and his only, genes to further a flock, herd or band.
I agree with appps, .... head chicken thing. .... and if she is squatting for you, then she ( he thinks ) prefers you. ... He is trying to mark his territory - as is his right.
I think you have to come to some peace within yourself - ( and only you know and can do this ) ... as to whether you want him because he's been with you a long time, or an Australorp which you obviously would prefer. On the other hand, an Australorp roo might well display the same tendencies, if 'black chookie' prefers your perceived 'advances' to his. !!
I have no idea how many chickens you have overall, and how their coops, runs and free range is arranged. My only suggestion is that you isolate your chicken(s) / rooster from everything else with some more wiring --- clip ALL wings including his ( after moults ??? has she / he / they all finished moulting ? ) ... and thereby stopping any flying over fences to attack, particularly your children.
But that solves one problem only. .... You are way bigger than your rooster in size and HE KNOWS IT .... which is why I would suspect he is trying the 'passive' ways of blocking you, crowing at you. etc...
As for the postie ? ... seen as another intruder into his harem ( of 1 or more ? ) ... it is so very natural for the "male-capable", of any species to protect his flock. ... Personally, I would never 'crow' back at him - would be like red rag to a bull, even if you managed to remotely hit the right note !!!!
And yes - as appps suggested - keep him ( or ANY rooster at full-on mating time ) away from your children ... just as you would not allow them near a bull in a paddock full of wanton cows, or a full-on stallion around mares coming into oestrus. .... Very dangerous stuff.
Good luck with your decisions.
Cheers ........
