I sell eggs and chicks from home. We also free range our flocks.
I 30 laying hens 6 roosters. I cannot have hen or a rooster running around that I don't trust.
And I don't have that much time to spend on one bird.
As I posted in this tread before we have a roo in our axe pen for this very reason.
I prefer to hand raise my roosters because it is easyer to teach my little girl to work around them and they are used to her.
But yes if they go bad we love bar-be-que chicken.
There is a couple of ways to deal with this;
1.Put blinders on the roo
2.Get a chick and hand raise it.
Behavior training takes time a dose not always work.
We have RIR roo in what we call the axe pen for this very reason. A rooster can jump high enough to hit a child in the face and he may not stop once she go's down.
