1. Do roosters love any female, do females love any rooster. These are all young (less than half year old and less than a year).

2. Would siblings know each other even if they were separated soon after hatching? Do siblings mate?

3. In a free range situation will there always be male fighting? Will they just have their own group rather than their own space? Our pet rooster chases them now but there was only a few fights. I am afraid when he gets older the yougher one will try to become dominant.

4. If you want to get rid of a rooster but not kill it can you bring it to an area where there are alot of other wild roosters? Would his mate be really upset?

I have one hand-reared tame rooster (cockerel). He is not a year. I have two other a male and female (siblings). They are Jungle Fowl that we kidnapped. We have had them since tiny chicks but didn't give them enough hand-raising so they still have wild in their blood. They are a few months old and we recently let them free. All have free range of the neighborhood(we live in a jungle). We just got another small female who actually is the sibling of the other two. We want her to be mate/partner with our pet rooster. I just let her free after too short in the cage. She is off by herself or her siblings, not with our handsome rooster.
Basically we want our pet rooster to be happy and are not sure having another rooster is good for lovin' or if we should keep adding females until one loves him?...or if we get rid of the onter rooster will they grow to love him??

Chickens do not "love" in the way that we know. Roosters will mate with any hen although my two roosters won't touch one of my three hens. None of the hens want the roosters to mate them but they do seem to prefer the company of one over the other.

If separated, siblings will forget each other completely within a week I'd guess. My rooster has mated with his mother and now his daughter/half-sister (the baby he made with his mother). Chickens have no concept of incest. Siblings will breed.

Roosters will always fight but they often have periods of truces where the dominant rooster is in charge. One day, younger roosters may challenge him. It's when they are equally matched that someone gets hurt. I keep my two boys apart as the son hurts his older father.

There are few places with feral chickens these days. Release of the rooster into the "wild" would not only be illegal (in the US) but also cruel for the rooster. He would probably be alone, eaten by predators, scared, or maybe pester some other people. I suggest building a separate cage for the loser rooster. The dominant rooster should have access to the harem, or he will be mad. I am lucky in that my dominant rooster is sweet to me while his father attacks (or used to; he's getting too old now). If your dominant rooster is overly aggressive to people or the hens, you may want to separate him instead.

You live in a jungle? Where? Jungle fowl are from India. Do you live there? If so, then I guess they would be native and could be released.

Hens don't love roosters. They may trust them to protect them or allow them to be close to them. If the jungle fowl rooster is dominant or more attractive to your hens, then you'd have to confine your special rooster in a cage with whatever hen you wanted to mate with him. Chicken breeders keep pairs in cages all the time. I don't think a cage is good long term but for a short time, it may be okay.
