Just as a note, this early after laying the eggs can be uncovered even in cooler/cold temperatures without taking harm ... don't know if that will apply here, but until they are abandoned or discarded, don't count them out.
Note about leg injuries with peregrines - for males it is less serious than for females - females must stand and support both their weight and the males during copulation. And the females, generally do more of the incubation, and almost all of the brooding over at least the first couple of weeks of brooding. 19K can roost on one leg and can also lie down to rest/sleep which will help recover from a soft tissue injury. Anecdotally from Manitoba, Fiona turned up this year at the Radisson with a very pronounced limp and after a couple of weeks she was fine. Same applied to one of the Logan chicks, such that I thought I might need to rescue him/her (sorry, can't remember who it was) but by day 3 it was better and by day 5 you wouldn't have know there had been an injury.
I know it won't make it any easier when checking the cams & reports from Lincoln, but it really is a wait and see for both 19K and the eggs, but it is much too soon to right them off. Cautious optimism and a little patience ... not easy I know.
