So, I'm now at 6 birds showing symptoms. The new ones just have the rattling noise so I'm hoping I caught it early to help reduce swelling and congestion. I know we can. Ot introduce any new birds to our flock until these ones die but what kind of preventative treatment should I do once we (hopefully) get these girls cleared up. I've read a monthly treatment is advisable but how?like, treat them all for a week with how I'm treating them now or?? Good news is the 2 that I found last night when this all started are doing great right now. The swelling has gone down a ton and they ate today and roamed around the yard. The bad news is my quarantine space is holding 6 sick birds because I'm trying to keep them away from the 8 birds that arent showing symptoms.
