My chicks are hatching under my broody. This is my first time ever. I have her in a seperate broody pen which has a small place to walk around, eat and drink and is attached to the run but has a door between them. When should I open the run to them? Right now I have 8 pullets that should be laying any time and one banty rooster that is friendly. I have blocked them from the run so I wouldn't have to worry about them hurting the babies. Also the broody is top of the pecking order but has been out of the coop for about a week. WIll she protect them? Can I let them out to free range as I do all of my other chickens? Also, can chicks walk down a little chicken ladder to the ground? The broody pen in about 2 feet of the ground. Here is a picture of one of my babies.

Thanks in advance for all your help.
