Re CG: It's a kind gesture of yours (ofc.) but birds cannot do anything when an egg has fallen to the ground (broken or not), I'm afraid. Also, think birds have a different relationship with their offspring (or eggs) than we humans have. Um, how to explain this? Dunno.. Less close, less intensely so, I'd say..
No, no.. not going to do so.. too long a story to vent my stance here now.
