I am new to chickens, and come to realize what I did was a big no no now but i cant undo it. I had bought a 19week old cinnamon queen from a farm store back in july[end of month] then a few days later bought my now 13 week old buff from a local farm, then decided to get three more pullets a few weeks later went back to the farmer and bought my 3 almost 9week olds. They all have been in the same coop which is the witchita cabin coop i built. When i got the buff i noticed she would sneeze here and there, then i noticed runny poops. And I decided to use corid as a treatment for 7 days 1.5tsp to gallon and treated all 5. I am still using the corid because it said to use 14 days after the initial 7 days as a preventative at 1/3 tsp per gallon which is what they are all getting now. I will have completed the 14 days on the first of september. I have noticed since using it the buffs comb looks a little less pailer its more red now. I also put BOB in their water along with the corid today i plan on giving them the probiotic for 3 total days. I also decided to go ahead and worm them and gave them the correct dosage of wazine on the 15th of august. I plan on following up with Valbazen on the 24th of August. I have noticed in the last 2 weeks or so the 13 week old buff just seems to be closing her eyes during the day she isnt fluffing her feathers. Today I wanted to weigh all of them and when i picked her up I noticed she sounded like she had flim or something stuck in her throat. I do have the 10% baytril i think its generic i got it from gamebirdsupplies. Its the enfloxacin 10% injectable and figure i would try to see if that helps. But i wasnt sure on the dosage with her being only 1 lb 12 oz
