Ever since some of the other hens have gone broody, my alpha hen is acting like she is broody too. But she's not. She's still laying and doing business as normal. When she is in the nesting box she does the cover stance and squawks at us. When we pass her in the yard she fluffs up and does the velociraptor growl at us. Is she being protective of the other broodys or is she just confused? Its funny to watch.
