We have 6 hens and 1 rooster just wondering if that is enough hens for him
My basic laying/breeding flock is one rooster and 6 to 8 hens. Some years 6, some years 7 or 8, depending in what happens. I know you read a lot about it on this forum but to me the ratio is not what is important. One very thing important is that each chicken has its own individual personality. You can never tell what behaviors you will see with living animals because of that. Sometimes you get lucky, sometimes you don't.
How much room they have can be a factor, though I don't think a lot in this case once they mature. When immature it is more important. Any behavior problems you have are magnified if they are squeezed tightly together.
One very important thing is that right now you do not have a rooster, you have an immature cockerel. The pullets should be old enough to behave like mature hens. Until that cockerel matures enough to behave in a way to impress the ladies, they probably won't think he would make a good father for their children. So they probably don't want to have a lot to do with him. His hormones can drive him wild and he has little control. He wants to mate them, a lot. That's not really about fertilizing eggs but the mating act at this age is about dominance. The one on the bottom is accepting the dominance of the one on top, either willingly or by force. I once had a five month old cockerel that could suitably impress the ladies but that was rare. I had one that took eleven months to reach that stage. Most of mine average around seven months. I think the girls have a lot to say about that too, it's not just the male. The girls have their own personalities, some are more willing to accept a male as dominant than others.
I don't know what you are seeing in their behaviors. Watching them go through adolescence can be very hard to watch or it may be no big deal. At some point things should settle down as they all mature but watching them go through adolescence may not be for the faint of heart. It's a lot like humans. Most do grow up but some remain immature brats their entire life.
It's not a matter of ratio. Some people with one rooster and one or two hens don't have issues. Some people with one rooster and over 20 hens do. But one big part is whether you are talking about immature cockerels and pullets or mature roosters and hens.
