yes you are right.
Follow KJ's advise and you will be okay
Also may I suggest this,
when the chickens get sick from anything their bodies get E.Coli infection that needs some biosecurity to help them get well.
Here is what I have done and would do now for all the chickens.
WET MASH PROBIOTIC RECIPE FOR CHICKENS WITH ANY HEALTH PROBLEMS
WET MASH PROBIOTIC RECIPE FOR YOUR CHICKENS HEALTH.
ACV by Bragg's is sold by Amazon and at Walmart. (remember to get Bragg's as it has the "brown mother" in the bottom of the bottle.)
My Daughter JoAnna Mertz feeds this wet mash probiotic several times a week to our 10 hens, 5 buff orpingtons 5plymouth rocks, and they are eating it up in 30 minutes.
