Sick ducklings, help!

[Melbi90]

Open mouth breathing is temp
What is the temp it’s at and how warm is the room they are in ?
How big is the brooder
Can you show pics of the full set up

It sits around 80 right now. This is what I have right now. I planned on less ducks but I'm in the process of building a bigger brooder. The heat lamp is as high as it can be

It sits around 80 right now. This is what I have right now. I planned on less ducks but I'm in the process of building a bigger brooder.

That is pretty small for growing babies
Could be why the bigger are to warm
I buy these small pet panels and they work great as brooders
I can start smaller and add more as they grow to accommodate them
When newborn I use the solid ones and as they grow a bit I can use the cage like ones
Here is my brooder set up
I sectioned half of it off for this batch of little ones but it will be expanding in a few days as they are running around now
I also use some for outside time on nice days but stay with them as I have cats
I get mine off Amazon

I have cats indoors so I'm unable to use open containers because I don't want to risk it. I also have young kids and can't guarantee they won't leave the door open accidentally to whatever room I have the ducklings in. As I said I'm definitely working on a larger brooder right now. When I got this one I had initially planned for only a few weeks in here and also many less ducks. Lol I greatly appreciate your advice!
