Doe suddenly dead, question

I just discovered a dead doe this evening in the pen. I seen this doe on Friday night, she was completely normal and healthy and was the first to rush into the feeder and eat just like she normally is everynight. Yesterday I went to a church leadership seminar all day long and got home just in time to feed before dark. It was pouring down rain and none of the deer came up like they normally do when i dump the feed in, because of the rain, so I didnt see her last night. Anyway after church this afternoon, I went into the pen with my dad to put up some shade cloth and looked down and seen a white belly. My first thought was the buck got aggressive with his antlers and killed her, but there were no marks anywhere on her. No blue tounge either, She was bloated, but that could be that she was dead all day saturday while I wasnt home. The only this odd i noticed was thick yellowish mucus in the nostriles. Could she have really gotten sick from the day and a half of cool rain and die that quickly. It looks like a respitory issue with the mucus but how could it kill so fast. on Friday, she did not look sick at all, but it was 70 degrees and beautiful, Friday night it got into the upper 40's and started raining and didnt stop until this morning. the only change in my routine was some terremycin crumbles added to the feed the past couple days to help keep peak body condition before the rut. I lost a yearling buck back on Aug. 7th, he didnt look sick on the 6th, but it was a cool rain that night before and i found him dead with the same yellow mucus in his nose. If you saw my deers body condition, you would not question their health, the are all thick and healthy, i take great pride in their great body condition, that is why I am so upset that these seemingly healthy deer die without giving me symptoms of illness, to help them. For those who have dealt with pnemoninia, how quick will it kill, did the deer give you a good sign they were ill? I am worried now, I will have to watch the herd very carefully this week, hopefully this dosent spread. I cant handle another loss, I have been in this buisness 3 years, and havent even sold a deer yet, that just makes it more agonizing when you lose one. Also this doe just had a fawn on July 30 Im sure she was still feeding him, I hope he is ok, He is still kind of little with his full spotted coat.

well, would it show up in a necropsy. I didnt get time to get out of work to get one on the doe that died. But guess what, my biggest best fawn was absent from the feeder last night, I figured thats ok because they sometimes dont all come up. Well becasue of the doe dying the other day, when i got home today I immediately went to check for him. Found him dead, way out on the other side of the pen no apperent reason. I must get a necrop or something done before the other 21 deer are dead, there is obviously a disease now. how long can a necrop be done after death. This one has been dead for probably 2 days, and already has an odor, is it too late? Its unfortunate the way my pens are laid out, I really try to check on all of them everyday but it is wooded so it is hard to notice everyone. Im really bumming now.

Thats ok, I just got done dragging him out, He was bloated and had just a little odor, i couldnt imagine anyone wanting to deal with him so i buried him. I am just going to count on prayer. The Lord cares about me and my deer, if he wants them all he will take them and there is no changing that. I will continue to watch carefully the next few days if any would start to look sick I will vacinate. For now I drained and scrubbed the water tub, even though Its well water and it is changed every 3 days i dont want a chance of this spreading. I will be darting and moveing a buck and 4 does this weekend to switch up the breeding pens, I will give some wormer and antibiotics to those that I move. Every deer came up to eat and looked as healthy as ever tonight so we will see what happens. Even though this situation sucks, im going to continue to stay positive, I admit when i saw this buck fawn dead I though for a second I should just give up, cut the wire let them all out, this isnt even worth it. this was my best pedigree on the whole farm, It is just sickening to see one dead after you make all the effort to feed and care for them to the absolute best of you ability. But I still got plenty of deer I am excited about and I will trust the Lord that this is a far as this "mystery illness" goes. Thank you all for your imput.
