A friend of mine, Kenducky, has along with his ducks and chickens a brood of four guinea fowl which were reared under a broody hen, with a rooster who watches over and protects this odd family.
The guineas are now fully grown and are bigger than their foster mum.
Recently after this family having roamed around the field together for months, one of them has taken to staying in the shed, and if it dares to venture out is instantly set upon by one of its siblings and forced back inside.
The imperious rooster who protects them all from animals and humans alike seems to ignore this behaviour between his adopted family.
We do not know the genders of the birds, so have no way of tying it in to this.
Has anybody witnessed this behaviour, and is there an easy way of telling the sex [ie curly tails in drakes]
