My button quail hen has been acting strange ive seen her shoving eggs under her lays on them for a while she picks up hay and puts it over her back then stays for a bit leaves wanders around then lays in the middle of the tank naps their heads to another hidey spot sleeps for a bit in that spot then goes back again to sleep on the eggs then the rest of the night she sleeps with the other hens outside the nest she made, does anyone know what this means?
