I have 3 buff orpingtons i got about a week ago, they were about a day old when i got them. today i got 3 new chicks that are probably a couple days old. can i put them together or keep them seperate?? the 3 buffs are pretty bouncy and play alot and jump around and the 3 i got today ( 2 barred rock and 1 rhode island red ) are really really calm and relaxed and dont even run from you. When i got home i put the babies with the buffs for a second to see and the buffs sort of started staring them down and they tried to peck them, so i seperated them right away and they are now in seperate cages. should i keep them seperate or were they just testing them or checking them out or what??
