Lost my whole guinea coop

[Permabirds]

Looking for some help today, I had a flock of guinea fowl for over 4 years started with with 6 when i started lost 2 to a fox 3 years ago so I bought more last year (20). going into this winter I had a group of 18. Two nights ago I gave them mineral in their water and I put heat lamps in as it is getting to be 20 degrees or less at night. I checked on them yesterday and everyone was fine, this was the day after their lamps were added. Not sure if the mineral water did it or the lamp or possibly some disease??? but they are now all dead but 2 when i went out this morning and the 2 are acting weak. I have 5 chickens in there and the chickens are still in good order so I am at a bit of a loss as tow hat it could have been but obviously with so many dead I want to check into it. The only other factor I can think of is I gave them food scraps form thanksgiving that had some turkey in it so maybe it had something that got the guinea's but would not affect the chickens??? Any and all help is appreciated.

Ill see if i can, its the red bulbs from orchlens in the chickens isle (250 wt I believe)

Used the same bulb for the last part of last winter and did not have anything like this happen.
