I have successfully hatched chicks under a bantie sitting in a pet carrier, which I placed in a rabbit pen, so the chicks could come out too. I also pick them up at boot sales, and charity shops for a few quid!! I will move them in the dark, and see if the reluctant ones are more co operative. I tell you what, banties are small, but they can give a nasty nip when you lift them off their nest!!
Hopefully get a nice selection of chicks, as I have a variety of colours among the bantams. Should be able to sell no bother, as people are always asking me for the bantam hens. Obviously I will end up with mostly cockerels as usually happens.
