Weight loss is only an indicator of relative humidity coupled with shell porosity and is not an indicator of the embryo growth within.
Happy hatching! :jumpy
...None of those have zipped in a natural way. The white membrane is the freshest one and the dark one has been like that for a bit longer making it *probably* the least viable. The hen has been pecking at them, possibly trying to assist.
I would at least candle them and give them the sniff...
...feed routine.. regular feed, treats, and supplements.. and state that coupled with genetics.. I'd not rule out symptoms of ascites.. as this *can* be how it presents (sometimes before other symptoms become apparent).

Noting that all...
If air sacs are truly small.. you'd want to lower your humidity not raise it. What color are your eggs?
Too small of air sacs may cause drowning or malposition as it could allow the chick to grow too large to turn into position for hatching.
The incubator read out should never be trusted. Can...
If you're talking about aquasol, it doesn't claim to treat tapeworms.. it claims effecacy against round worms and cecal worms.. and only adult life stages at that (possibly what you saw on day 2?)..

Last time I sent a bird in for necropsy to UC Davis.. the cost was $40 for 2 birds. I looked it up and it appears to be $35 for 2 birds from a backyard flock..

Sooner is better than later.
Use the look but don't touch method for at least a few days or longer if needed.
I've had great success doing this.
Hope it goes well for you also! :fl
You could always add Orpington of other colors.. Cackle has silver laced (also jubilee and lavender)..

Not sure about availability but Meyers has several color offerings including Jubilee, chocolate, blue, and...
...despite being a regular layer.. and that (EYP/internal laying) may not actually be what's going on.. just one possibility.
The slight bounce you feel on the abdomen *could* just be a little fat pad.
Hopefully she will continue to thrive and you will get more feed back and considerations! :fl
Sorry for your previous loss. That won't do anything for internal parasites, if suspected.. as stated on the package.. it does not work in wet conditions, such as the digestive system.
Another consideration *might* be internal laying, sometimes called EYP or egg yolk peritonitis.
Looks like possible lash material.. sometimes called lash egg or salpingitis. Consider cutting it open and seeing what it looks like on the inside.

Turken is a breed and nacked neck would be a gene or type. The naked neck gene will pass on to other birds and is incomplete dominant.. which produces the bow tie according to my current understanding.
By mixed color flock.. I mean all Turkens but of different colors varieties like black, buff...
...And was also the sweetest boy, until he wasn't.
He should not be dancing for you.. that's an indicator in my experience, of things to come. And *possibly* that he's imprinted on you as part of the flock and/or pecking order. It's a sign of dominance towards you.
Hopefully it won't progress...
Turken is the breed.. they are likely from a mixed color flock rather than individual colored flocks. Unfortunately, many hatcheries are using mixed colored flocks.
I can't make out Splats' whole neck, but chickadee has what's known as a bow tie.
Sorry for your loss. :(
Sounds and looks like you're possibly having predator attacks..
More information would be needed to try and determine which predator it might be.. like where are you finding them (inside the coop or out in the yard, etc), at what time in the day, where are you located...
...symptomatic in the whole flock.
If you have any others present with symptoms and decide to cull.. (refrigerate and) sending them in for necropsy *may* give you more answers. The following link has the contact information for the state poultry labs.. sometimes free or affordable to backyard...
