Better to say 4 roosters is too many for 4 roosters. The 6 hens can wait a bit and soon there will be one rooster a-go-go, one in the hereafter, one running away, and one squating on the ground. The hens could deal with 6 roosters, but the big boy a go-go won't stand for more than him with his flock. actually 1 rooster needs 5 hens to be satisfied other wise roosters will fight One rooster will service (fertilize the eggs of) up to 6 hens. If you have more than 6 hens, you will need another rooster. 4 roosters on 6 hens is not good. The roosters will fight and the hens will be exhausted running from all the roosters.

Roosters need hens, 5 or more should keep them happy. 5. Most important, they need food and water.
