not sure what's wrong with my 9 week old... over the last 5 days I ve noticed a decline... still eating but not much... my chickens were moved from the brooder to the coop 4 days ago but I noticed the change before the move... I have found bloody stool but I don't think it's from this chick.. and it's only been a little bit... chicks are still on medicated starter feed... pine shavings for bedding... pls help
