Thx DARKBROWNEGGS....
unfortunately we have built up our flock over a period of months mainly due to cost, some birds being older than others but most are point of lay...... we believe this one bird had slight pecking when we got her which probably enticed the other birds to continue.... we have no hierachy issues and have a very large Handsome Cockerel who keeps all the birds under control and in the whole they all get on well.... we have a very mixed flock including light sussex, marans, legbars, black rocks and warrens. We have recently purchased two gorgeous pure breed Buff orpington hens along with a young Buff cockerel who are housed separately as we intend to breed from those and dont want cockerels fighting.
We will follow your advise and remove the young maran and bring her home to live alongside our 2 ducks that live in our garden, hopefully her feathers will come on quickly and she can be reintroduced.
thx again for your advise , as i posted in my previous topic we are new to this and fascinated by the life of chickens all help gratefully received.
