I am new to the whole egg laying process, anyway, yesterday was my birthday and the chickens planned to make me a present by making eggs for the first time! they are small eggs but they are young hens (four months and a half).. I have three questions: 1) One of my barred rocks when you try to pet her lowers her body and opens her wings slightly, almost like a cat in heat.. what does that mean? It just started yesterday, she looks fine otherwise... 2) do chicken get upset when you get the eggs? they seem to complaint a bit when we get them... 3) the egg laying song after making an egg, what is it all about? what makes them do that? does it hurt them when they lay eggs?
