I don't know if this has been answered somewhere but we were just wondering why a couple of hens toss pieces of straw on their backs after they lay an egg. The RIR started doing this since day one of egg laying & then we noticed that the Silkie did, too. Is this some sort of bragging thing (like a tally mark) to let the other girls know that they have laid an egg or what? They're both about a year old and none of the other 3 hens do this that we know of. It's just comical to watch them reach down, pick up the straw & then toss it onto their back as if to say "yeah, another days' work done!" and walk away. Crazy birds. Just curious but does anyone else have hens that do this?
