I've managed to raise 15 chickens just fine without any illness. I picked up 19 chicks from TSC during chick days and I now have at least one hen who is ill. She is sneezing and making gurgling sounds and even gasping for breath. She sounds just awful. I read someone's earlier post on gapeworm but I can't imagine how she would have been exposed. She is only 2 weeks old. I have had them all on medicated starter. Should I quarantine her? Duramycil-10 on hand but I don't know if it is OK to give to chicks this young. Any advice would be appreciated. I live out in the country and the local vet already warned me he doesn't really know poultry.
