I have 5 chicks of assorted breeds. One is sitting in the pine shavings and moves kinda to her side kicking out the shavings from beneath her .It almost looks like she's burrowing. I picked her up to see if there was any obvious problems and she did not jump up to get away. Just concerned she may not be feeling well. She's normally one of the more active chicks . I am only 2 weeks into my chick experience any advice is welcome .
