HELP BIRDS DIED OVER NIGHT

[Jak115]

We just lost seven birds, they where all acting fine yesterday and this morning i found them dead in their coop. There was one with blood coming out of its behind and no other injuries and i have no clue what happened or what could have caused this

How old were they? How long had you had them? Any changes to the coop, feed, run, etc?
Pictures of your set up may be helpful.

they where only about three months old, nothing has changed and il get pics.

Did you see any change in droppings, any bloody or mucousy droppings? Check your feed, any change in consistency, color or odor could indicate spoiled feed.
If you still have the bodies, refrigerate them, don't freeze, consider sending one or two off for a necropsy, that is the best way to know for sure what happened.

my boyfriend spotted a blood drop last night in the coop but didnt think anything of it, this morning there was bloody diarrhea on the ground

That sounds like coccidiosis. Some strains are more virulent than others, and it can be fatal quickly. It's most common in chicks and young birds. Treatment is usually Corid (amprolium), available at most Tractor Supply stores or feed stores. If you have any remaining birds I would start treatment as soon as possible and hopefully you won't lose more. Corid is very safe, and won't do any harm even if it was something else. Treatment chart is below, use the severe outbreak dosing, and make sure that the medicated water is the only water available. If any are having any symptoms of lethargy, sitting puffed up, not eating or drinking, or you know they have abnormal droppings, then give them an oral dose in addition to the medicated water, dosing for that is here:
