i'm not a vegan or even a vegetarian, but i'm not naive enough to pretend that the animals used to get milk and eggs are happily sitting in fields waiting for "a little tug on the boobie" or for someone to come take their eggs.  Egg farms are atrocious.  Dirty, smelly, terrible conditions for the chickens.  My husband's family works with several big dairies and the cows don't see the field.  Their exercise is walking from the barn to the milking parlor and back again. 
I work in agriculture, so I know that not all farms are like this.  If you have a chance to buy from a smaller operation, you should.  But to suggest that the processes for procuring milk and eggs is humane . . . . It suggests the rather large disconnect that the family farms are always bemoaning--not enough people know where there food comes from.
