Hello, I have read so many of your posts regarding chicken health and I am a bit freaked out. Of course, I didn't read until I had already got the chicks otherwise I would have never received started chicks because this has been a terrible thing so far... anyway, I received these chicks last Thurs and immediately my husband said NO quarantine it is stupid and they are just chicks throw them in with our chicks. I didn't want to do this but he said it was too cold to put them in pens alone so I did it. I watched them for a long time and noticed that one of the chicks was really sleepy and when I picked her up she had a runny nose and watery eyes. I immediately took them out of my coop and noticed she was coughing. I swept all bedding out of my coop and bleached all of the feeders, waterers and roosts. My flock is not showing signs of runny nose or cough but, i am still freaked out. Fast forward, Sunday I noticed 3 of those chicks are now coughing and the biggest pullet has a yellowish discharge out of her nose and is breathing with her mouth open. One of the chicks is also passing blood in their stool. How should I proceed? I have added ACV to the water of all my birds I am bleaching my shoes when I go around these birds and I do not get near my birds until I am sure I am clean.
