I have had two 7-month old pullets go broody without much warning. The first (Silkie-Polish-Mille Fleur x) was happy to be transferred to a dog crate and sit on an assortment of eggs, which are due to hatch this week. The second, an OEG, sat for the first night and then seemed agitated and wanted out of the crate. I had put 5 OEG and 2 standard eggs under her. When I let her out of the crate all the OEG eggs were gone and only the 2 standard eggs remained. Why would eat them? (I haven't had any issues with egg eating) And will she continue?
