one of my cornish X pullets, 20 weeks old. Been getting random eggs for two weeks, one here and there. Heard the egg song but couldn't catch anyone in the process. Frustrating that is. So today I managed to catch one in the act. A cornish X pullet. Makes sense now that the eggs haven't been in the nestboxes; the CXs being entirely clueless and all that. ETA this footnote - "clueless" being a nice way of saying dumber than a box of rocks.
