Mine are on lockdown now anyway due to Mrs Sparrow hawk
At least it's not our lively hoods at stake !! It is a particular concern to the commercial poultry farmers as their feed costs will go up, diseases among housed birds will become a higher risk once winter sets in and of course after 70 days housed they can no longer be classed as free range so their product value will decrease
The trouble is due to all migratory birds there is very little that can be done to prevent unless the bring in compulsory vaccinations which again increase production costs.
it is a worry as each year it seems to get a little worse
