Are Australorp Roosters really agressive

Every rooster is different, although some breeds tend to be more aggressive than others.

That being said, I've never met a ''nice'' Australorp rooster. The ones I've been in contact with r very big & very mean. After the age of 18 months, most end up in the stew pot. I am not a big fan of that breed. This breed in particular has been used for cockfighting because of their size & temperament.

Your bird is currently a cockeral & is therefore immature. Most roosters will come into their own around 10 months to a year, & I prefer to use roosters that r about 2 years old for breeding purposes. Usually, by the time they r sexually mature (about 1 year) is when you're going to see how the personality & temperament really is. Hormones play a big factor in how they behave.

A rooster will usually start crowing & trying to mount hens by about 10 months to a year in age.

However, by hand raising a rooster, it helps (but does not guarantee) that u will have a docile, friendly adult rooster. Continue to handle him daily & u stand a better chance of having him continue to be friendly. Aggression in roosters is usually from that bird becoming territorial (over their yard & their women). If he sees u as an intruder or a threat, then he is more likely to go at you.

Hope this helps!
