My hen hatched 6 eggs about a month ago. She's been a great mother, very protective, but over the past 2 days she's started what seems to be a process of making the chicks fend for themselves. It began with her moving farther and farther from them, ignoring them when they squawked for her. Today, however, she actually seems to be hiding. Twice I found her huddled in the back seat of the car (she got in through the window) while the chicks ran around like crazy outside looking for her. Is this normal? Should I be worried? I'm considering putting her in a separate coop for her own sanity. Any thoughts? The chicks are all quite robust and large so I'm not as worried about them as I am about the hen.
