I handle my chicks every other day, & it works out fine.Out of 3 roos, 1. Very nice, worst thing he ever did was peck my leg 2. Same as 1 but mean to humans when he was around unknown roos 3. He was mean! Pecked when touched and overmated the hens, we sold him, someone wanted him for his frizzle gene
All 3 were in together. I say if you want nice hens AND roos, mess with them as chicks. I understand if you have 10 chicks it is nearly impossible to hold them every day. If you cannot play with them while young, then get the crock pot ready.
