Chickens suddenly dying now sneezing and losing color

[crazychick_17]

Hello, we acquired some baby chicks back in april. Just within the last week two of them have died. The first showed no symptoms, she was acting fine then we woke up to her dead in the coop. (12 weeks golden laced wyandotte) The second chicken was the next day started acting lethargic, this particular chicken is a runner and escape artist but would not move at this point. (14 weeks Crested cream legbar) If moved she would stand hunched for a minute and lay back down. Eyes closed, beak to the ground wings and tail feathers droopy. We brought her inside she was eating and drinking, made it through the day night and next day and passed the follwing night. she did have diarrhea that was watery white and green. Neither of them showed symptoms prior to this. Now a few of my other chickens have started sneezing, (a cuckoo maran and spotty CCLB) I have a crested cream legbar who has white spots on her feathers, her poop is a deep mustard yellow and a little runny. any idea what's going on or if these are related? I have attached a picture of the one who passed after bringing her inside and of my CCLB who has these white spots showing up (the one looking in the picture) temperatures here this week have been 100+ they do have access to water and food at all times as well as shade covering.
Thanks for any insight!

Well it could be about a hundred different things. Hazarding a guess may send you in the wrong direction. The only way to know is to send a bird to your state poultry lab for necropsy and lab work.
If you tell me your state, I can post your lab/s.
Call them and ask how they want the bird sent. You can send the next one that dies or better yet, send a sick live bird for more conclusive lab results.
What have they been fed since April?

I am in meridian Idaho. they have been on a medicated chick starter feed and there is a layer feed available to our hens as well that they have access to. they also get kitchen scraps.

If they've been eating a significant amount of the layer feed, that could have been a problem with the bird that died suddenly with no symptoms.
It wouldn't cause the sneezing issues though.

Could it also cause other bone issues? I have a barred rock who cant walk on her leg, she just drags herself around a bit. She's in a seperate area, but as a result of little movement she's getting poop build up frequently posing issues of it's own.
