So i just baught a few Buff Orpingtons 4 cockerals and 3 hens. When i got home i noticed that a cockeral was making a snoring sound when breathing, and often gasps for air. This mornging i braught him to the vets and she said that he needs antibiotics. And the chancers are the rest of the flock i got has it. I havent paid him all the money yet. So what should i do? Ring him and say they where sick, and then what?
