Not looking good.. Deformed hatchlings

[Aercadia]

It's a terrible situation to have to face with a shiny new clutch, but you may end up having to cull the deformed babies.

;n; I can hardly imagine having to make this call. I know this is an awful subject, but if these babies cannot thrive and culling is the best (if heartbreaking) option, what is the kindest way to do so?
