I have a quick question about nest box bedding, how deep does it need to be? I have a new hen, none of my pullets are laying age yet, and she seems to be unhappy about the nest box situation. She has inspected several, but is rearranging things and scratches and squirms down to the bottom of the boxes - then leaves unhappy. Do I need to put more bedding material in there? I am not expecting her to lay for a few days at least since she has only been here a few days, but I want to be sure the nest boxes and nesting material I am providing is ok. In some boxes I have a few inches of straw and in 3 others I have a few inches of pine shavings. I am excited to see "our" first egg and I don't want to put her off with the wrong stuff or wrong setup. I think what we have is suffecient, but I wanted to double check. Lemme know.....and thanks!
