My Reply : In terms of chicken
'love' bribery usually is the most likely to work - regular visits
with a handful of treats can bring them rushing to the door every
time they see you. If they will let you pet them and pick them
up that can also be a good thing to do ocassionally as it builds
up their trust (useful in case you ever have to handle them for
some other reason). When chickens are young they often don't get
the hang of roosting at night and sometimes even huddle together
on the floor so it may just be their age that caused them to sleep
in the nesting boxes. They have a natural tendency to want to
go to the highest place to roost so if the roosts are higher than
the nesting boxes they should, in theory, prefer the roosts (especially
as they are now used to them).
