How do I know if a chicken is a full grown adult?

[Kr1spy_dreamz]

i have a few young chickens and 2 older hens, last month i had one of my roosters attempting to breed with one of my older hens at a very young age (it is a deleware)! 3 months as an estimate! Since this month one of my other younger roosters tried to attempt at mating with one of my younger hens! And she hasnt laid a single egg yet! She did not let it luckily. So i was wondering, does a rooster become a fully fledged adult if he attempts to mate? Or are my 2 roosters just doing that because of there testosterone?

They're teenagers until a year old usually. Able to reproduxe, but not adults

What breed is he? Some birds mature faster than others (ie. Fayumis take like 9 weeks to mature, jersey giants take usually 7-9 months )

The one that tried to breed with one of the older hens last month was a deleware, the one that tried breeding with the younger hen was a barred rock

How old are these birds, in months?

No. They are fully grown between 1-2 years old.

Or are my 2 roosters just doing that because of there testosterone?

Probably. Cockerels start to try and mate as early as 10-12 weeks old.
Having more then one male can create an environment of competition and they all can be at their worst behaviors.

Breed doesn't really matter....it's all about the individual birds.
