i am new to having chickens and i have 2 orpingtons and 2 marans..they are all 4 weeks old. and yesterday i meet a lady to buy a three cochins. i did not know when i went to get them they were bantams. i thought they would be standard. but i had drove a long way to get them so i went ahead and bought the little ones. they are the cutest chicks ive ever seen! but now im really worried that when they are able to be in the same coop will my other girls hurt them? any info will help.
