I was thinking more long term solutions to prevent it not kill them off after the herd is infected, and I was hoping you would know of something besides have me look up possible solutions.
Why not give them some feed with antibiotics in it? Chlortetracycline is a general antibiotic put in some animal feeds that kills bacteria, and the pneumonia is commonly caused by some bacteria. Here's an abstract on the common bacteria that causes pneumonia in wild sheep.

Abstract
The authors have performed a comparative study of the efficacy of various in-feed medications for the treatment of 5- to 6-week-old specific pathogen-free (SPF) piglets experimentally infected on day 1 with Mycoplasma hyopneumoniae, on day 8 with Pasteurella multocida (serotype A), and on day 15 with Actinobacillus pleuropneumoniae (serotype 2). The treatment started on day 9 and continued for 12 consecutive days, then the piglets were euthanized for examination of macroscopic, histologic, and pathologic lesions and for the presence of mycoplasmas and bacteria in the lungs. Based on the results of clinical observations (respiratory signs, rectal temperature, body weight gain, and feed conversion efficiency), macroscopic and histologic lesions of the lungs, and microbiologic findings, the best results were obtained by treatment of pigs with Econor + chlortetracycline, followed by Tetramutin, Pulmotil, Cyfac, and lincomycin + chlortetracycline.
Maybe more would survive with something like that applied?!
