Hi, I am still extreemly new at this. I have found a home for my 6wk old roosters but have noticed just now that one is acting sick. I don't want to go giving anyone a sick rooster It is making a crackling sound in it's chest when it breathes and is walking around with it's eyes closed. Can I help him? Will the rest of my roosters have the same thing? none of the others seem unwell or are making the same noise. I can't give away a sick rooster, but should the others be ok?, don't want to do the wrong thing by the person that I'm giving them to.
