My chickens are 11 weeks old and last week I noticed one had a foamy eye. She was acting normal and after doing some reading on here I thought it might be a infection in the eye or nasal cavity. Started vetrx right away in their water and directly under her wings and on her head until I was able to get terramycin. But now I have another one that is wheezing and sneezing. She is acting normal, not mouth breathing, she is eating, drinking, and running around just like the rest. I am putting the vetrx on her as well now. I just ordered the tylan 50 powder from jedds. Is there anything else I should be doing?
