We believe we have 4 boys and 2 girls. 2 boy Campbells, 2 B Pekins, 2 G Pekins, not completely positive though. By the looks of them we thought we only had 1 B pekins that is quite larger then the rest of ours and with a curled tail yet says quake, the others are very quiet when they quake. The Pekins are 4mo and the KCs are 3mo. Will they be alright staying together as a group or what do I need to do?
