Sounds like the game I had to play last year with all the cockerels I got. In a box of 20 assorted bantams I ended up with 17 boys and started my rehoming process at about 8 weeks old.
I began with the ones that simply didn’t look good enough to me, then by breeds I wasn’t as interested in, then the ones whose personalities I liked the least, then deciding on the nicest ones to my girls. The final cock was rehomed because I didn’t like his crowing habits and thought his brother had the prettier face.
I had to buy more chicks to make up for the terrible numbers and got a stunning boy in that group of 12, so by 5-6 months old I’d whittled it down to 2 males out of 21. Several months later, my favorite chick from the get go is still my favorite rooster, and my beta roo has his good qualities but may be a tad rough on a few of the pullets. I may reevaluate keeping him as my first batch of home hatched chicks mature.
