10 week olds with 14 week olds or adults ??? I have 3, 10 week old pullets, who I would like to move so I can give their space to my BLR girls who have outgrown their space. I have 2, 14 week old pullets. I would like to put the 3 in with the 2. They are very similar in size, as two are siblings (4 weeks difference), their mom must have bantam in her lineage as they are both similarily colored and similar size. the other 14 week old, was my runty one, who also isn't very big, so the size is not a major concern. Just wondering if the pecking would be more aggressive with youngsters or oldsters. Both sets hatched on my property under broody hens.
