My chicks are eight weeks old on Monday and the book says they're old enough to go out. They've been out in the day for a while now. When they go out at night do I close them in the enlcosed bit or leave it open till they get used to it? and do they need access to food and water at night? Sounds so soft but I'd them to die becuase I did something really stupid. And is there ever a point where its safe to let the dog free range at the same time as the chicks? Don't think she'd hurt them but she's def interested. Thanks in advance for your help.
