I have a bantam americauna hen that's been disappearing for more of the day for the past two weeks or so. She'll show up in the morning for a half hour to an hour and then won't be seen for the rest of the day. She'll gorge herself on food and water while she's out and about, and I try to make it as accessible for her. She isn't acting the same either, she's more anxious and she's making the growling sound that broody hens make. Does anyone know why she's doing this? I can't find where she's spending most of her day and she isn't coming into the coop at night. I've attached a picture of her (sorry she's wet, it rained a ton today) and a pic of her manure. Any help will be greatly appreciated!
