Larger broods do allow the chicks to bond more with each other than humans.
If your intent is to make your chickens pets, then I would give away the excess now so that others likewise can bond with their chicks.
On the other hand, if your idea of a friendly chicken is one that comes running to you when you go out with the treat bucket and then follows you around in the yard, all you have to do is be the treat person. Flock size doesn't matter much then. The bolder ones will run up to you and often allow handling which will encourage the shyer ones as well.
However, even with frequent handling as chicks, many birds become more stand offish during their teen months until point of lay. Some revert to purely flock behavior, especially for keepers who work most of the day, which I personally find is healthy for the bird.
Never force a chick (or adult bird for that matter) to be handled if it doesn't want to be. Also avoid the big hand coming down from the sky as that will kick in their prey instincts to run. Lay your hand flat on the ground with palm up, holding treats, and you will have adoring chicks.
As they grow, make verbal sounds (cluck cluck or chook chook) when you approach the pen, and use a treat bucket to draw them to you. Always allow them to approach at their initiative. You will soon have several who adore being picked up and petted, while others, not so much but will tolerate it.
I have no problem with them admiring me merely for the treat bucket. I am not looking for lap pets in my chickens.
If, though, you wish lap pets, then consistent, friendly handling is required understanding that some birds will never truly appreciate being petted.
