Is heat exhaustion a real thing for chickens?

Does that coop have any open windows or other significant ventilation?

How many birds do you have in this?

I'm guessing there were originally about 10 based on earlier posts.

I'm looking back through other threads/posts by OP.
I see some new birds were brought in in April.



OP...
How many birds to do have total and what are their ages/when did you get them?

10 is way too many for this little coop.

He apparently has older birds in a larger building. The chickens that were dying are the ones from April.

@ChickenCanoe hit the nail on the head.
Your chickens do not have a disease; they are dying from heat stroke and the organ failure that follows.

You should consider that chickens are not the animal for you if you cannot check on them daily and provide the basic necessities of food, water, and adequate housing space.

This would be correct, but I believe it was actually early march that we got these birds. So even though they are consuming food their bodies cant digest it due to the organ failure? As one of them has been eating the last 3 days and still acts weak, its like the personalities changed all together as they dont try to escape the coop like they used to do every time I replenished water and food. There were 11 birds in here before this lovely fiasco happened... now its 4 and 1 barely holding on rooster. beyond this we have 12 hens that are almost 3 years old and yes they are in a much bigger run/coop now, free ranged a lot at night, this coop is 12 feet by 10 or so. All sides of the small coop are hardware cloth except the back side.

Being with out water kills.
It may have done irreversible damage to your remaining birds.
This coop is too small for 5 birds.

The only thing you can do is cross your fingers and hope they survive.
I would continue the Corid for a full round of treatment, just in case.

Here is the coop setup currently.

This coop is maybe 2 feet by 3 if that big.
I can tell based on the size of the green chick feeder.
