I bought some birds last weekend that were in outdoor pens with netting on top. This area has been hit hard by rain lately and the pens have been very wet and they had so much poop, the whole place stunk. One or more ~ not really sure, have a real watery stool. They are between 4 & 6 months old. 2 Buff O. and 2 Light Brahmas. Is it ok to treat them...to be on the safe side? Thanks!!!!!
