I have a black australorp rooster... he's about 5 months old or so (all of my chickens are the same age). in the past couple weeks i've noticed that he's started to limp and it was getting worse for a while. in the past day or two he seems to be slightly better, but today i noticed the his right wing is lower than his left (which the right leg is the one he favors). it's almost like he had a chicken stroke or something. for a while i thought that our other rooster was picking on him... but i have no real proof of that. the australorp rooster is definitely not as developed as my alpha rooster, so thats why i thought that victor (barred rock rooster) was picking on him. i took a video of him tonight but i dont really know how to post it (any advise on that would be helpful). please let me know what you guys think... i'll post a couple pics too!!
