My hen hatched her brood of three about 4 days ago. Since yesterday she's scratching or digging like, making small clucks and walking backwards, but she's not fully standing while doing this.. She hasn't done much since she's had them.. Maybe she's going a little stir crazy? The chicks were peeping really loud for about half hour or so in one instance and they kept trying to get under her to warm up but she wasn't really letting them? Any ideas? I hope she doesn't neglect the chicks...
