I have read, and according to one of my chickens, it takes about 25 hours for an egg to form. I think it varies from chicken to chicken by a few hours though. New laying hens will only lay every two to three days while an older one will lay about once a day. I don't know at what point the shell actually hardens but it is hard when it comes out of the chicken. I'm sorry I don't know exactly how it is formed either but I do know that there is a small pocket below the tail where it is formed. Older chickens will lay larger eggs as they get older.
