we have one cockerel that is super sweet and my daughters favorite so I’m hoping to at least keep him. She calls him Pumpkin.
UGH!
That would be the one that would HAVE to go first.... in MY experience.

I had a fantastic loving and sweet lap cockerel... who became a giant wad of raging boy hor mones that waNted to mate and didn't have any fear (respect in the chicken world) of me. He KNEW I was not a threat. And soon commenced to trying to pull hens out of my lap. Once put to the boy side... I felt something brush the back of my leg and thought nothing because he was standing there all innocently. Another day, I felt something again... so commenced a chase of my own. Tried all the rooster training they talk about, but he stalked me from behind the fence, charged me, and pretended to do busy work when I looked, crowed at me. But this was my SWEET boy, and a rare breed anticipated breeder who already passed the cull for faults and was a beautiful specimen. I tried to work with him and gave him a chance to mature past it. That was my first rooster experience and ALMOST ruined me by the time I finally decided I had enough of being attack when my back was turned and relentlessly crowed
at.
Now that won't be the case for all sweet boys... but please be aware that it is a possibility.
A rooster that avoids you is actually a good thing. He respects your space. But Leghorn boys are known to be aggressive... though it's probably a true stereotype... One thing I have learned is that ALL birds regardless of breed tendencies ARE individuals and will behave as such. He does look like he could be a barred Rock. Also possibly a sex link, I think.
It's true BYC really tries to come together and be a safe and helpful learning community. Glad you found us!
What age is your daughter? Maybe look into the correct way to handle boys and start working it now... so he might be able to stay and be a great flock head for you!
One thing MOST of us here do understand... is that what may or may not work for you or someone else may or may not work for me. We are here to share our own personal experiences. There is no truly wright or wrong way (well there is actually) but the RIGHT way is the way that works for YOU. Always feel free to get a second opinion on ANYTHING you are told, ESPECIALLY if it came from a feed store employee. Just because they are your neighbor or friend doesn't mean their way will work for you. But it might. WE do our best until we learn something new and then switch it up if we need to. I have seen some terrible things, but we aren't here to judge. WE are here to help and we ALL make mistakes.
I like to have one roo for every 7-10 girls. Recently my rooster gave his life up to protect his favorite hen, so I think they're extremely useful although I don't like having fertilized eggs.
Very sorry for your loss.

Do you wanna share a pic in his honor?
This is ONE reason I don't think they are useful as protection...
Some will give their lives while other will duck or run for cover. But those that gave their lives... were just a sacrifice. Most the predators here will scoff at a rooster, as are simply NO match... Though I did accidentally get spurred by sticking my leg between two sparring boys... and way VERY surprised at the force with which my big boy connected! So they CAN provide SOME protection, but not MY reason for keeping them as I consider it inadequate for my area and needs.
But I do LOVE the beauty that roosters bring... and I really enjoy hearing them crow! It's so much fun to see them drop their wing and do a little dance for the females. They call them to treats and even a little warble type serenade.

Make no mistake crowing has ZERO to do with the sunrise and starts here around 3:30 AM EVERY day. I don't hear it unless I'm awake getting a drink or using the restroom. And I guess my neighbors are far enough away... because they WOULD let me know. All my neighbors know that while I have the right to do as I please... I please to live in peace and be considerate of them.
Wish to note there is NO difference between fertile and infertile eggs as far as any average person can tell, when it comes to eating.
