I am raising my first flock of chickens, six Rhode Island Reds. One of my girls has lost her red color around her face and is tired wings are drooping and tail is down, gets up and walks around and eats but you can see she is tired. I held her around her chest and she felt too bony , no meat. I read another thread here and it sorta sounded like what I may have, WORMS! I bought some Diatomaceous earth and mixed some in with my feed as advised by my feed dealer. Any opinions on what may be going on with my girl would be appreciated.
