I have four Guinea chicks. They have been raised by a Pekin bantam hen. All has gone well so far though she has been alarmed by their insistance on flying to the highest point to roost at night. She has managed to keep at least two at ground level. They are kept in a 12' x 12' horse stable. My husband has solved the problem by putting a branch up to the rafters and she now climbs all the way to the top and they look so cute as she insists on wrapping her wings round the two she can reach!
