Here is my best way to describe what's going on:
My hens are getting sick 1 about 3 years the other few are like 3 months.
They seem to have some sort of liquid or flem in there airway and makes it sound like there not breathing well, there also lethargic and seem to sneeze a lot, a few of them wheeze when I pick them up, my buff Orpingtons comb is turning black slowly and she's not laying eggs anymore.
They have been showing signs for about a week and a half but I didn't think much of it at first.
There are 10 birds in the pen and half of them have the same symptoms,no signs of trauma or bleeding.
They are eating and drinking , they are dinking a ton of water , like so a concerning amount.
I feed them kalmbach 17% layer feed!
Poop seems normal and healthy,I haven't done any treatment,.
