I had a mama hen hatch 3 eggs from 3 different hens we have and a rooster we have they were all raised together outside the mama protected them but there was never any fights or anything, now these hens are 16weeks old and it’s like I have 2 gangs the older hens and rooster do their thing and the 3 pullets separate themselves and do their thing when they all go in at night they sleep at opposite ends of the roosting bar. I know the top 2 hens kind of will peck at them if they get in their way but shouldn’t they be merged and establish pecking order by now?
