I have an Ideal 236 breed (white leghorn) that keeps sitting on eggs. She doesn't say on them. And she won't go in the nest after I take the eggs out but if there's eggs in there she climbs in and moves the eggs really close together and sits on them. She'll sometimes stand up and move the eggs closer and tuck them under her breast. If I try to touch her while she's in the nest she pecks at me. I don't think that breed is supposed to be motherly, they're breed to be great layers not mothers. I know she's not full on broody. Maybe she's just praticing. Or maybe she's a nut! edited to add: She's sitting on an EE egg right now.
