Last week we noticed our rooster was acting sick. Lethargic, not eating and slumping down. I removed him, gave him antibiotics in his water with electrolytes for 2 days or so and he's all better now. Moved him back to the flock and noticed this morning my bantam frizzle is acting similar. Can i just give the whole flock antibiotics in the water to prevent them from all catching something?? Or do I have to pull each one as they get sick.. My rooster seems back to himself.. but this morning when i checked on them my frizzle seemed sleepy and wasn't pecking for scratch with the others. Whatever happened with my rooster antibiotics/electrolytes seemed to cure him Thanks for any input! Going to make some antibiotic water now and syringe her with it.. but I'd like to just add it to the whole flocks water to hopefully prevent more from getting sick?
