This is my first time hatching eggs with my broody silkie Middy. I got 6 fertilized bantam eggs and put them under her last night. She seemed very happy this morning running at top speed to do her business, eat and drink and is now back on the eggs. We have a small coop that is raised from the ground about 2.5 ft and has a little ramp going down into the pen. She is in one of the two nesting boxes right now. After the babies hatch do I need to keep the door to the coop closed so the babies don't fall out or will she take care of them? Will plan on putting food and water in the coop for them but didn't know how long she would be happy confined to the coop. Plus my other silkie Stormie goes in and out to lay. Any advice would be helpful. Thanks!
