I need them to be giving enough to easily life several men off the ground at a time and be a threat to dragons but not so huge they are bigger than a castle.
A relevant piece of information is what kind of dragons do you have in your world/story and what can the dragons do to fight with a roc? The stronger and larger you dragons are, the same goes for the roc if its supposed to be able to be threat to them.I need them to be giving enough to easily life several men off the ground at a time and be a threat to dragons but not so huge they are bigger than a castle.
The idea is they live as long as the rider and the riders are elven so a few hundred. By the time they are in their last 10% or so of life span they hit a growth spurt that makes them the biggest creature in existence (but these are very rare there are 2 in the span of the books and they are only that old because they had 2 riders not 1).So, that description rules out the mythical version, which was said to be able to lift up elephants in one or both it's claws.
Picture probably not needed, but cool anyways. But that thing would be a decent threat to a dragon. Still, figure maybe a twenty or thirty foot tall birdy to get at least a couple people on it or to hold. So, more or less the Eagles from LotR size or a bit bigger.
My dragons resemble the ones in Last Airbender serpentine but with 4 legs and huge wings. They can breath fire and are capable of speech. Generally they are wild and almost never seen. The older they get the more power they aquire (there is one who is a thousand years old who can change colors like a cuddle fish, and manipulate water but can't breath fire) the most common are fire breathing dragons but you have a few elemental dragons such as the one above which is a water dragon.A relevant piece of information is what kind of dragons do you have in your world/story and what can the dragons do to fight with a roc?

A mix of naturally via bird anatomy and wind manipulation.If rocs fly 'naturally,' their size would certainly be restricted by physics (of course, they could be larger in a world with lower gravity). I've kept my flying dragons and griffins reasonably small for this reason. If magic (or some unknown science) keeps them aloft, I guess they could be made as large as fits your story needs.
Lol. Probably cause a bald eagle should be able to carry a goat fairly easily for some distance lolOn a more realistic note, I recall seeing a video of a harpy eagle fly upside down–or damn close to it—to take a ~20 pound sloth off of a tree limb and fly away while making it look easy. On the other hand, I had a bald eagle in my front pasture a few months back struggling to haul off a possum. He'd fly about 50 feet and land... wait, fly 50 feet... Possum coulda been fighting, I'm not sure.
I will probably make adolescents this big.As big as you want really. My rocs were about the size of very large horse.
Don't mess with a roc!Roc have a bigger size than dragons are resilient against flames and can manipulate wind to incredible degrees usually (so no oxygen no fire)
