Not as easy as it seems.

I'm fairly new to raising chicks, I've got 2 three month old mille fleur d'uccles I've raised, one month old bym chicks I hatched and raised and now two to three week old chicks 2 of which I hatched others I bought from rural king.
I have never had a problem until just recently. After coming home with the chicks from rural king the Ameraucana chicks I hatched (9 total, not including the ones I sold before this) started to suddenly die. I did the research, got the medicated food, changed the bedding, gave the vitamins, cleaned the butts. I did everything right and for some reason they just kept dying.
I am left with 2 out of the 9 I hatched and trying to do everything right for these babies.
I built a brooder out of pallets (not very experienced with building so try not to judge too hard) I assume maybe the problem was overpopulation? Still not sure. I was using a storage bin which worked for the others I raised. I primed the inside with mold & mildew paint and let it air out for a few days before moving them into it. They seem to be very happy with the room, even started to play and got the zoomies. No problems since.
If you have any advice for this newbie please do tell I won't take offense, just want to do what's right for the little ones! Mostly just wanted to share my story as they all seem to be doing great now so I think (and hope) it's over.

The brooder looks fine. I'm so sorry for your losses! What symptoms did you notice in the ones that passed? Perhaps the new chicks brought something in with them that they already had a resistance to but the ones you hatched didn't.

The only things I noticed other than fatigue, in some not all was bubbling at the mouth like they couldn't swallow saliva not exactly like foaming. Never found what could've caused this either.

I'd disinfect everything really well before bringing in or hatching any additional chicks just to be safe. Without tests done it would be hard to pin down the cause. That's really a shame you lost them.
