I assume you have a rooster. Since you don't know when she started, don't give up. If they are her eggs, they all started the same time because she won't lay more after she starts sitting. Another possibility is that other hens will volunteer eggs after she starts every time she leaves the nest...
It isn't common but does happen with some frequency. If you hatch enough, you encounter all sorts of strange things. I once hatched a 3-legged chick. Accidents happen.
Introducing like numbers and like sizes is the least problematic. So adding a single chick to any group of adults is fraught with complications but especially with RIRs.
That may be the best approach except you have to be there. Maybe a way to automate it.
It will definitely simulate a setting hen. Hers are on their side and she scratches at them, she doesn't mark the eggs so I doubt she has any idea how far she turned each egg. Perhaps that's why they do it so...
As you know, legislators can construe all types of reasons to outlaw activities of citizenry. Even if unconstitutional, it would have to be challenged and courts would have to side wth the challenger.
However, I think you should relax. No one can predict the future. I live by the idea that you...
That depends mostly on your ambient temperatures. For the last few weeks, baby chicks could have survived outside here comfortably. It doesn't even get out of the 80s at night.

IMHO, a lone 6 week chick will gladly accept friends after the initial shock of interlopers...
A lone chicken, especially a young one will gladly accept friends. The first few hours or a day may be awkward but they will quickly take to each other I've had lone chicks a month old or older quickly adopt chicks as young as 3 days. Your best bet is to get two or 3 chicks. Most stores will...
Tilting could solve the turning concern to a point, but I see one or possibly two problems with tilting the incubator.
One is how the water reservoir is designed and spilling.
The other relates to whether it is a still air or forced air incubator. Problems with incubation will occur if it is...
If she's acting normal and not lethargic, I don't think there is reason for concern. It may be a bit early but molt has to happen every autumn. The earlier than molt is likely due to her being broody for a time.
Where are you located?
If a feed is made at a local feed mill, it could be of good quality, but without a guaranteed analysis, there is no way to assure the nutritional value.
Much more important is the age of the feed. That means the mill date on either the seal, the guaranteed analysis tag or some other place where...
Have you any evidence they had coccidiosis?
Since you have lost 4 birds to the same condition, my advice is to send this bird to your state poultry lab for a humane euthanasia and necropsy. That is the only way to know for sure what you are dealing with. This will give you a plan of attack so...
