all birds can lay unfertilized eggs, but in egg farming, we keep chickens separated from possible mates, so the eggs we get from egg farming are almost always unfertilized (unless there's a very sneaky rooster). our birdman would have to be capable of parthogenesis. he's only laid a few eggs before, the rest of the time his cycle was suppressed, and it seems there was a lapse in care.
it's pretty common for birds to be attached to their eggs. they don't understand the eggs being unfertilized. it takes weeks for them to realize the eggs aren't viable. it's also true that eggs can get stick and egg binding can be dangerous, although slurping on cloaca isn't the treatment but uh.
so probably not
Will the eggs hatch??? Because he was sad his eggs always disappeared and all right so will those hatch??
