Guineas and Polish chasing/attacking younger chicks

[CatWhisperer]

I have 4 guineas and 6 Polish that are 18 weeks old. 13 ‘Onagadori’ and serama that are about 15 weeks old. And 10 mixed LF and bantams that are 8 weeks old. The guineas an Polish live in a coop peacefully with seramas and silkies that are 2 months older than they are. The younger chickens coexist peacefully in a separate coop. All free range about a 1/2 acre fenced area with 3 different levels and lots of trees, plants and shrubbery. The guineas (who have chosen the largest Polish cockerel as their leader and the separate group of 5 Polish are always chasing and sometimes attacking the younger chicks. There are feeding station and water bowls spread all over. The 15 week olds spend most of their day hiding in their coop, they are also afraid of the 4 silkie cockerels. So we lock them out some days. Is this behavior something the guineas and Polish will outgrow ( and when)? Or do we need to start eating them?

The guineas will not outgrow this behavior. It will only continue to get worse. Your guineas are acting just like I would expect guineas that are raised with chickens to act. They do not have the ability to understand that the chickens are not guineas. When breeding season starts, they will get even worse.
