I finally heard back from Lancaster fancy fowl that two of the four pullets I was waiting on (and already filed a claim with PayPal against) were ready. I really needed two more birds to help the first two I have to overwinter, so Against better judgement we drove the 1.5 hours and picked up a blue copper marans and an Easter egger and re-paid in cash. The auto shop we picked them up in is smoke filled since the owner smokes at his counter, so there was no way of detecting a smell. On the way home we noticed a strange odor, but figured it was due to having strange birds. The breeder told us that to incorporate these two with my other two, I should wait until dark when the other two go to roost and place these two on the roost next to them. They'll have all night to adjust to each other calmly and all will be good. That's what we did. This morning the smell on these two new pullets was very strong and the marans had snot stuck to her beak which the Easter egger kept picking at. I have separated them but I fear it's too late. We have no avian vets in the area and our (dog)vet said they don't treat exotic animals. They don't have signs of lice or mites, they're eating ok although not drinking much. Their poop seems ok, and they're 'foraging' in the pen I enclosed them in. I am new to all of this and don't know what to do.
