Oooh! Good advise! I certainly will not EVER bend down where he could get to my face. He is not playing at all! When I had to treat him for lice once my husband and I had to get our gear on and go out at night while he was on roost and he had to hold him while I did the treatments to him. Thankfully it worked! He was none too happy about it but he didn't wiggle around too much. Just glad I had his help to hold him. No way could I have ever done that by myself even at night. He's probably really peed off now that he is in a pen by himself and has no ladies right now, He was a maniac and was loving my poor Red Riding Hood RIR to death, had to remove him since she would stay in her dust hole under the chicken house where he couldn't get to her, most of the time. He is huge and much bigger than her. I would like to have some of those hens though, I have 2 that are from him and the EE that I had that got eaten in the pen. They look mostly like him and are solid black with the green iridescent feathers and fat and pretty big, but have the puffy cheeks like their mother the EE, she was solid white, and they are both solid black with 1 tiny white feather on their necks. LOL They lay bluish brown eggs, not a really pretty color for an egg! :/ I've never thought about having to file any rooster spurs, don't quite know how you would go about doing that, seems like an impossible chore to me! UGH!!!!
Like many things, you do it enough times it becomes an easy task. You would need help the first time. Use of large dog nail clippers like the Miller's Forge brand are generally good for spurs and nails on large birds. An emery board, steel dog groomer's file, or even a Dremel with a nail bit works, just be careful. Have some blood stop powder, chalk, or corn starch by your side when doing it in case you get too close to the quick of a nail or spur. The "quick" on a bird is that main vain running through the core of the nail or spur. With periodic cutting and filing of the nail or spur, the vain recedes with it over time.The foot must be held in a comfortable position, and not allowed to move during the process. A strong jerk will break the spur at the base, and you don't want that. With a Dremel or file, buff the end of the cut spur so it is flat or round and smooth. Healthy chickens naturally wear toe nails down by being active foragers, and rarely need cutting
A rooster needs hens or he will become more agitated. I don't like having any less than 10 hens with a young virile rooster, and they must be of proportionate size for an Australorp rooster. Too large of a rooster will injure or kill a hen. Of course, I recommend hens of the same breed and plenty of space. Even so, roosters will have their favorites, and that may need management if one hen is bearing the brunt of most mating. You'll see missing feathers on the back from the rooster's breast bone rubbing from prolonged mounting. So long as the skin doesn't become sore and irritated, it is alright. That is also another reason to keep nails and spurs filed smooth, as it can cut a hen.
There's a big difference between standing your ground with a rooster and encouraging him to fight as you may know. This is why it always annoyed me to see people tease a rooster, or act excitable around them. Confidence and calm consistency with routine makes a difference.
Dust bathing areas like Centrarchid mentioned are anywhere loose dry soil exists, but can be provided as well. Wet weather determines much. His analysis of the California Gray was accurate, though I disagree about encouraging aggression towards them, as with any rooster.
