meat birds get bigger faster, and still lay eggs.
They can be free ranged, too, without any problems.
They might pick on the smaller chickens though, so separation might be something to look into if this problem occurs.
cornish are prety hardy as far as chickens go, since they are not bred for temperment or eggs, just for loads of tender white meat...and diseae resistance.
If you're looking for yummy flavor, the cornish have it.
If youre looking for eggs, they have it.
If you're looking for yard decor, they are still chickens!
Maybe this is a happy little surprise in an unexpected package!
