One of my first chickens had a respiratory Disease and I was given medicine from the vet... She died sadly from worms Now a frizzle I bought has it. I found the medicine that I used for my other chicken and it says " half a CC twice everyday... How many days? IF I can remember I THINK he said two weeks, but I could be wrong! Anyone know this answer? Would like to start treating him ASAP, but I need to know this first! Thanks!
