There is only one chick (1st hatch) left at this nest.
Although I don't feel up to viewing the 2nd hatch, I was watching the 4th hatch (Terzo’s egg) when Hope removed chick from shell and fed to C1. I do believe she knew something about the 2nd and 4th hatch that we could not detect.
C3 (3rd hatch) died during the night while Hope was brooding. I don’t believe this death was intentional and felt very sorry as Hope paced back and forth while gently trying to nudge the chick - several times - but to no avail.... Terzo and Hope continued brooding the deceased C3 along with C1 (and the 4th egg) until the next day - when Hope decided it was time to stop, and the remains of C3 were then fed to C1.
Maybe the eggs were affected by less frequent incubation while Hope had to hunt on her own (after E2 died). She also had to spend time finding and bonding with a new mate, though I'm sure there are many other things to consider. I've come across several opinions regarding Hope - and some were quite interesting; however, (in my opinion) there simply aren't enough facts.
Thankfully, C1 (E2's egg) is growing very well and receiving plenty of attention from Terzo and Hope, and I’m hoping this adorable chick will live on to enjoy a happy/healthy future.
