I have all females (pretty sure, they were all but one sexed as pullets), and two of the definite females like to fly up and sit on the edge of the brooder. I found personality determined how they liked to fly up and whether they liked me or not more than breed, but my prairie blue bell is definitely more flighty than my ISA browns and buff orpingtons, and my starlight green egger is less fond of me than the others (per breeder description). I've gotten my prairie bluebell and green egger to calm down and be more relaxed around me with consistent calm handling. Takes a few weeks, but be persistent and slow and try not to scare them. Around 3 wks I started given them a bit of chick grit mixed in their feed and soldier fly larvae/mealworms (1 larvae per bird twice a day) - treats helped them see me as a positive presence. Also they like to perch on my warm hand. I'm new to chickens, so don't take my word about on treats, you might want to research that yourself - I check for crop emptying every day, add apple cider vinegar and electrolytes/probiotics to their water, and feed just enough treat for excitement. Good luck!
