I have no idea about feed, but resting on their knees is fine so no need to worry :)
Sounds like she's lucky to have such a caring owner to spot something like that though :)
Also, lying on their sides for long periods of times isn't good for horses, if I'm not mistaken. Its not a bad thing if you see it, so don't worry, but lying with their legs tucked under them is fine :)
If she rolls, tries to bite her stomach, kick her stomach, is sweaty amongst other things, these are signs of colic and a vet should be called and you should get her up and walk her, not allowing her to lie down until the vet has seen her.
