I think they are two weeks old, suppose to be 2 weeks old.
You are correct...they look very small for 2 weeks which is another reason you should start Corid.
Having coccidiosis can be tearing up their insides so to speak and not allow them to absorbs the proper nutrition which could be why they are small.

The person I got them from said they were 2 weeks. The ones that died were the smaller chicks too.

I highly recommend you get some Corid.

View attachment 1529779 (this pic taken at 8 days old). how old did you say your babies are? mine were hatched on aug 29 and at 11 days now the have wing feathers and pretty good start on tail feathers. from your newest pic, i’m not seeing the same progression for chicks over 2 weeks old???

Here's a better picture of two of them

I shouldn't give them nutri drench and corid at the same time, right? Or does it not matter?

Correct...do not give the ND while on Corid.

ND ingredients:

Corid=Amprolium:

Should I wait for the ND to get out of their system before starting the Corid? If so, how long?

No. Start Corid immediately.
Did you go buy some?
Powder or liquid?

I got the liquid kind. How long should I put it in their water for?

I use medicated chick crumble.

Dumb question - since the medicated feed already has amprolium in it, is there a risk of overdosing when adding the same medication to the water?

I agree with others that changing your brooder and starting corid will hopefully prevent any more losses. I (in no way claiming to be an expert) just cannot logically justify the significant developmental delay without considering a miscalculation or misunderstanding in age. The pic of the original chicks developmentally look like normal 2 day old chicks and the most recent picks look right for 1 week (which is the amount of time you have had the original survivor) by the calculations given, if they were 2 weeks when you got them and have now had the 1 for almost a week, that would mean that they are now 3 weeks old showing a developmental age of only 1 week. I realize there is some variation as in my own 15 (my little hoppy is still behind by a few days but he has a significant leg defect for which the hatchery refunded full price of chick.)
