Do larger roosters breed more?

I was recently given a large rooster as a gift from a friend of mine, I believe he's americana? I already have a New Hampshire Red Rooster who way over mounts my 10 hens but has fertility issues and only seems to produce male offspring :/

I was thinking about replacing him with the Americana but I'm afraid the heavier male will also over mount my hens do to his sheer size!

Do smaller roosters Mount more than larger roosters? Or is it Vice versa?

( PS I should probably also add in that the Bantam hens in the background are kept in a different coop at night with their rooster and I've never had a problem with the two flocks fighting)

Not an Ameraucana or Easter Egger. Not sure what he is. He might be a mix of some sort. He’s pretty though.

Also, I don’t think any of them mate any more or less depending on size or anything. It just depends on the individual rooster.

I've had three roosters in the past half year. An Ameraucana, a Cubalaya, and an Indio Gigante. Despite having the longest time period the Indio Gigante (largest) was the least fruitful, and the Cubalaya (smallest) was the most fruitful

This may all be a coincidence and unrelated to size, however I suspect that due to sheer size fertility issues were part of the problem
