I've lost two of my cochin babies (1wk old, hatched here) in the last day...and now another one has crusty eyes and multiple other chicks have a "click" when they breathe. I've given the crusty-eyed chick ointment, and have discovered that I can (hopefully) treat the URI w/bactrim/smz-tmps. The trouble is, I can't find the dose! I have SMZ-TMP 960s (800 SMZ, 160 TMP). I'm used to treating horses with them - I'm thinking I don't need to use 20 tablets 2x/day I have approx 50-60 chicks (had several hatchery shipments & hatches occur almost simultaneously, had several "orders" back out - now I'm overwhelmed!), and 1qt and 1gal waterers. The "least thriving" chicks are separated. Thoughts on dosages? I'd hate to wing it, but the best I can come up with at this point is...1/2 or 1 tablet in a 1qt waterer? But that's just a guess. PLEASE HELP! Before I lose more babies...I'm still searching for a dosage, but any guidance would be appreciated!
