I wouldn't force feed the starter yet, instead give her raw egg yolk. You can get that into her easier and it has all the nutrients she'll need.
In your pic I see 4 BO, 4 EE, 1 BR, 2 JG, 1 SS, the favorelle, the really light one is probably your light brahma (even though they usually have a little grey to their back, they don't always), and what looks like a silver polish from here - maybe your meal maker?

I had one like that last time and I just kept giving her water/electrolytes in an dropper every hour. I actually found her on her back. Thought she was dead and nursed her back somehow.
Now for my 5 DOA, the only one I can tell for sure is the barred rock, the others are all light yellow, one a tiny shade darker. My mix was. 5 Buff Orpington, 6 Easter egger, 2 black jersey giant, 2 specked Sussex, 2 barred rock and 1 light brahma, 1 meal maker and 1 salmon faverolle cockerel. I know the faverolle isn't dead because he has faverolle feathers that are noticeable. What else would be light yellow?
Here they are
