This is a very inaccurate assessment of the advice given by the people in this thread. Myself included. My main interest is what is best for the bird. Always.People that tell others to rehome are poorly informed and pretty much don’t give a crap about their pets.
This is completely contrary to what you wrote in the first statement quoted. I know of no one personally that intentionally does dangerous things with their pets.there are many things we do that are dangerous with pets
These boxes rarely if ever have adequate ventilation for the bird.dark box don’t let any light get in and let him out in the mornings
It's always best to provide an animal with the proper species specific environment, food, etc.
I do understand about getting attached to these guys. But if you are not permitted roosters where you live, either move to where you can have them or rehome them. This OP has many fine options for rehoming and the cockerel will be able to live a normal, happy chicken life. That is the right thing for the bird and the hard thing for the keeper.
