Rooster doesn’t mate.

[RoostersAreAwesome]

Just looking at his comb leads me to believe he may not have a lot of male hormones going on there. His comb is hen sized. A roosters should be much larger. I wouldn’t use him as breeding stock, but to be fair, you may want to wait until spring and see if the longer daylight hours cause his hormones to kick in.
Another thing to consider is are the hens older than him? Mature hens are usually unimpressed with cockerels and will even beat them up.

His comb is the usual size for an English Orpington.

The size of the comb is just fine for an Orpington rooster.
Here’s an example and a link to a site where they show standard/price winning roosters.

This info is from a Dutch site (Orpington club).:
Cockerels are very clumsy. As long as cockerels have not yet undisputedly assumed leadership (usually this is because one or more hens are higher in rank) they are very clumsy. Usually they are not courteous at all. Only when they are really THE cock do they start to behave courteously.

Some breeders even use Artificial insemination to get the sperm where needed.

I know someone who had an Orp rooster who did his job as be should and was a great caring and loving father for his chicks though.

Awwwww!!! He’s so cute though!! Too bad my Gerard isn‘t more like him. I love roosters but don’t really need them to fertilize eggs, and when they are big (my Gerard is a Buff Orpington - total sweetheart but too big for some of my girls), I’m always afraid of them doing damage to the hens (one of my girls required surgery with stitches because of Gerard - he now lives in his own pen right next to all the girls.
Well, good luck! I just thought I’d chime in about how adorable Kyle is .

I'm glad you decided to wait till spring, from my understanding some breeds take a long time to mature. If his crowing is weak than he's not ready to assume the role.

I’m having the same problem but for me nothing is wrong with my roo
He only mate with one female out of five so only her eggs are fertile and she passed away now he don’t care about the others

Thank you for the correction. I’m not that familiar with Orpingtons and didn’t know the correct comb size for them.

Hey guys! I could really use some brains to pick!
My rooster Kyle is an English Lavender Orpington. He is 10 months old. And he’s just not the brightest crayon in the box.

He crows, but he’s really bad at it. He’s not... much of a rooster. He doesn’t have any protective instincts, he won’t mate. Just doesn’t have any drive to be the breeding stock I need him to be.
We brought home a “seasoned rooster” thinking that Kyle would get the idea after watching (and maybe competing for a few weeks/months) nope. And then we had to butcher the seasoned rooster because he was a jackass.
Kyle is a very lazy bird, and he doesn’t seem to do well when it’s cold. The hens (jersey giants and black amaracaunas) do just fine in the cold and even choose to free range under the cedar trees where there is no snow. But Kyle, sweet stupid useless Kyle, just walks out into the snow lays down and waits to die.
As far as I know, this isn’t normal chicken behavior. He’s young, he seems healthy, but he has no interest in being a rooster and he’s really bad at just being alive. He also requires way more care than the rest of the flock combined.

I know that only time will tell me if things will change, but I could use a little bit of insight if anybody has some wisdom to share.

I don't know much but dose an orpington have other than white legs? I have a lavender with dark lavender lacing you can have.

Does he act ill?
It may be just his personality, I had a rooster, named Mary, that I kept separate from the hens in a pen with his brother, Blossom, but when I would now and then put him with the ladies, he would not breed them, his brother on the hand, was a true ladies man, even though he was partially blind.
Mary once bred one hen, but that was it.
So if he doesn't start to breed, which is usually at 4-5 months, then maybe separate him and get a better breeder.

Are you sure he is not a pullet?

He might be smarter than you think. He lies in the snow and gets to go inside to the warm house with a bowl of food and water all to himself.
