i think it would b easier if you hatched eggs and new from day 1 that they were gonna end up being butchered. If you just hatch some chickens as pets and they dont have any standards ie eggs or meat then it might b harder. I would never kill a hen or rooster that i hatched for egg laying. If i hatched them for meat birds then i dont think i will try to get as attached to them as i do the egg laying breeds.
