Are you referring to Columba livia or all columbiformes?

I believe that pigeons usually lay two eggs, although the generality of this 
could easily be checked in a reference book. The suggestion as to one for each 
sex sounds absurd to me and I have never heard that suggestion before. Let me 
know if I am wrong.

Your second point is correct. Pigeon produce a milky substance in the crop and 
feed this to their chicks by regurgitation. Although does it apply to all 
species of pigeons and do nil other birds do a similar thing?
