All battery poultry farmers get rid of their hens just before the end of their first laying season. Yellow pages may help you here
Without teaching anyone to suck eggs... here's a few tips from when we used to do this when I was a kid/teenager.
1) When bringing them home, don't put them outside as they did on Jimmys farm, the poor things will be scared stiff. Place them inside a shed or somewhere for the first day, then let them come out in their own time from day 2. They have never seen daylight before you got them, so no wonder its all scary

2) You will need to teach them to perch, they have lived on slatted cages
3) You may need to teach them to lay their eggs in nest boxes (this was usually easy - just place the eggs there!)
4) You may need to teach them to drink and feed
5) Start by feeding them proprietory pellets, this will be what they are used to, don't expect them to solely eat other items from day one without stomach upsets - introduce other foods slowly
6) They are unlikely to "know" each other, so expect some sorting out of "pecking order" this shouldn't be serious, as they are "all in it together" so to speak, and do genuinely appear grateful and happy.
6b) added later! - if you do get "hen pecking" deal with it with stockholm tar immediately...
7) They will bring diseases (this was why in the end mum stopped buying them, and we went over to "point of lays")

They will stop laying soon after you get them, they will have a moult, they will then recommence (depending on time of year!)
9) You WILL get attached to them - Egg production will drop dramatically after their 2nd season - think about what you will do with them then; are you happy with the occasional egg in order to keep them as pets? (this was why my parents in the end stopped having hens altogether as Dad hated dispatching them

) I did have a friend who kept all their hens till they died of old age, and one of them was still providing an egg a week in summer at an age I think of 8, but I believe this was unusual!!!
10) They will become the friendliest birds of all. I have a photo of me "cuddling" one when I was young! - it was very happy for me to do this

(but then again, I trained my rabbit to lie upside down in a pram covered with a blanket!!!)
Good luck
