Shipped hatching eggs 100% failed under my broody hen. What now?

[Back2Roots]

A bit of history: I was overseas in May when DH told me that my Silkie hen had gone broody. I organized to have a half dozen Brabanter hatching eggs shipped (because I've always wanted to have a Brabanter or two in my flock). They arrived the day I got home, and after letting them settle for 24 hours, I placed them under broody hen, who by that time has been sitting for about 10 days. Fat forward to day 18: I candled and saw that two were clear, three looked quite dark with a decent sized air sac, and two looked a bit iffy. So I stuck them back under her, and waited until day 21. Nothing. Waited another three days. Nothing. So I water candled them. No sign of life in any of them. :-(
But she's still broody. So, what to do now? Historically, all my attempts at breaking my hen's broodiness have failed, so I usually just let her snap out of it on her own (removing any and all eggs from under her daily, as well as picking her up and putting her out in the run daily).
I really do need some younger layers because my flock is aging, and I'm getting a lot fewer eggs (last winter egg production dropped to the point where I have had to buy eggs for a few weeks). I looked around for day-old chicks to graft under her, but most available chicks in my area at the moment are started chicks, about a week old, which I'm afraid she would reject.
I was talked into getting some more hatching eggs for her (local this time), but I don't know if I should give them to her... she may give up halfway through, and then what? I don't have an incubator. Most importantly, I'm worried that another 21 days of this will be too much for the old girl.

Any advice? Should I just wait for her to snap out of it at this point, or do you think she can handle one more incubation cycle?

I would say that this is all up to you. If you're willing to risk her stopping in the middle of it, (but you still have a chance of them being hatched) then try it. If you want to just let her stop being broody and get chicks, them that's just fine too.
Sorry I don't have a better answer, this is just about what you want to so, and not any laws of chicken keeping.

I'm thinking that another 21 days may be so debilitating that she may die. Can you get some sexed pullet chicks for her ?

@sourland, that's what I am worried about too: that she may die. I've been trying for sexed day old chicks to give her, but the youngest I've been able to find are one week-olds ((Legbars), and I'm afraid she will reject them. I thought I would be able to get some Welsummer day-olds, which can be color-sexed as day-olds with some degree of accuracy, but that didn't pan out either.
@12animals3, thanks for replying. I would prefer to have her stop being broody and adopt some chicks, but my other issue is that I can't have roosters, so I'm limited to getting day-old sexed chicks, and so far, no luck.

Another 21 days of her sitting would not be good for her, IMO. I would bet since she is a silkie that she would accept the week olds. I currently have a silkie and a faverolle mut raising 7 week old chicks within the flock. Another silkie hen, that wasn't even broody, calls the chicks over to give them treats and she also follows the two moms and babies around. I think it's just a silkie thing, they love being moms. A couple weeks ago, the faverolle mom decided she was going to roost at night but only a couple of her babies followed her up there, the rest cried in the nest box. The silkie mom saw those abandoned chicks, got out of her nest bringing her own chicks with her, and sat on that other mother's babies.
