So im still hopefull that Gracie can remain Gracie, but we have taken to calling her Dexter....I'm hoping you all can put my fears to rest. These babes are about 16 days old. I really wanted to add three HENS to my existing flock. So my question is, are they too old to add another baby to? I'd run out today and purchase a fourth if she will integrate with these three?? And is gracie a dexter?
