I don’t get this.But I will (have to) bring home another rooster, because I really need at least two roosters for my flock...
Nevertheless, I am going to be careful and bring one really, really young : last time I did, none of my roosters had any issue with the the youngest, and I think it was because I did bring him home when he was so young he was not sexed yet...?
Why do you need at least 2 roosters?
Why do you think a young roosters (cockerel) are better?
The worst age is often between 7 and 12 months old. These cockerels are often horny, many don’t submit to the master and they still have to learn how to behave to please a hen. Many people who like to keep 2 roosters finally rehome (or cull) one , to bring peace back into the flock.
In general only one rooster is easiest to have a peaceful flock.
To keep several roosters you need lots of hens and lots of space. The possibility to keep more, depends a lot on the breed/character of the roosters too.
It makes me wonder… How many hens do yo have? How large is the coop if they are confined to stay inside?
