Found wild duck eggs in backyard. Had seen the mom a while ago but now nowhere to be seen. One was already cracked/broken i think by a dog or animal. I left the eggs alone but started to worry after hour 3. I put them in a box with a towel on a heating pad. Temp inside is 95-97 F. Tried to call local wildlife rescue but no one picked up. Located in LA area. What to do?? I have no clue if they’re even still alive.
