Hello everyone! I come to you folks on a daily basis looking for help on this website, and you always have great advice. My issue is my daughter started raising chickens about 2 years ago. This will be her 2nd winter with them. She has gone from having 15 to 169 (I believe is what she's at now). My daughter (being 13) takes very good care of them with my help. While she's in school I tend to them through out the day & she tends to them after school & weekends. Sadly, I know nothing to very little about chickens. This year they seem to be very sick (this is how I came across this website). I've been reading up on every little thing to do for them. It breaks my heart to see them not feeling well Having so many, makes it extremely hard to vaccinate each one or to put medicine in the waterers not knowing if they are all getting the medicine they need! I'm convinced they have a respiratory infection. Those of you with larger flocks, what is the best way to go about making sure they all get the meds they need? I've isolated some of the weaker ones & have even brought a couple in the house to get better, but it seems like a never ending battle...any advice would be great! They sneeze & cough. Some have icky eyes, while others "seem" perfectly fine. We have had 3 die so far, by (what seems to be) no apparent reason?? I go let them out in the morning & everyone seems good by 10am when I check on them again 1 would be down? I'm at a complete loss.
