To my surprise when my 12 baby chicks showed up they were not 12 but 18! The Hatchery added 6 extra boys for warmth. These boys are definitely more "boisterous" that the others. They are constantly pecking and puffing up at each other and the smaller babies. They do not like to be held like the others. My concern is that the others seem to be patterning after these guys and getting more aggressive by the day (well... they are only 6 days old). I am committed to our chickens being sweet and family friendly. We will not be able to keep Roosters once they start cocka-doodle-doodling... should I separate them sooner rather than later??? Will not having the boys keep my girls sweet??? Even my 2 little bantam girls are puffing and pecking right back to these boys. Not very ladylike behavior. But maybe this is normal. Any advice would be helpful. Thanks!
