We have a broody Buf Orp. We are discouraging her now but might let her sit if she goes broody in spring. She is doing something I think is weird. Yesterday afternoon I went out to gather the eggs and found both two chocolate brown eggs laid by my Maran hens on the coop floor and the Buf in the nest sitting on 4 light brown eggs. This afternoon when I gathered the eggs she was in the nest box again with five light brown eggs under her. There was one chocolate dark brown Maran egg and one dark brown speckled Wellsummer egg (broken and eaten) on the coop floor. Could she possibly be sorting out the eggs that look different from her own? Or different from the majority of the eggs? I plan on getting her some Maran eggs to sit if she goes broody in spring. If all the eggs where dark brown will she reject them all or sit on them since they all look alike?
