I live in NE Texas, I have 17 hen 22 weeks old I got one chicken isolated in pet taxi in my warm garage she has been on tetracycline hydrochloride for three days resting still eating symptoms one eye closed kind of looks matted also sick acting didn't go on the roost after I noticed she had been making weird noises I thought she was just going threw female changes and was going to be the first to lay kind of a gurgling noise. I have bleached all my other water bowls and feeders and put them on the same thing they seem heathliy but notice a mild dosage of the same symptoms with the other ones the gurgling. What to do??? We just had a good rain last week and weather has dropped coop got a little damp.
