Envirogirl12--------------- a hen can be made to go broody, I have done it many of times.
GCkidd----------Im not sure what BO is, I dont know what for set up you have, like nest wise. If you have the metal 10 or 12 hole nest, then put her in one of the nest and put a cover over it so she cant get out. Like a piece of plywood. Put some fake eggs in there with and let her in there. Let her out once a day to poop, eat and drink, then put her back in there. Im telling you this way cause you say she is half broody. If she wasnt half broody then you would do the same thing the same way only put her in a box, with small holes for air, and keep it as dark as poss.
Depending on the hen and the breed, it may take a day or 2 or it may take a week or so.
Some breeds are not setters and some are really good setters.
I have done this with some of my hens many of times and it does work, but I have had a hen or 2 that it didnt, but most of the time it has.
I keep some mutt banty hens around because they like to sit alot and they are pretty easy to get to go broody. I also have some game hens and they are really good sitters and mothers and my cuckoo marans are great at it also and I can fit a doz under them where the banties I may only be able to 6 or so under them.
Ive only ever had maybe 2 hens that werent good mothers, in that case I gave the chicks to another hen or put em in a brooder. Ive had a hen or 2 not take another hens chicks, but most of the time they would.
I hope this will help you out. Good luck. Any more questions feel free to ask..............
