OK here is where I get slagged off by the experts.After about 5 years of doing things the proper way with the very best of advice on pairing up I.e. Cocks locked in boxes ,fronts securely fitted,hens introduced after great preparation etc.etc.I have reverted to the way which was most successful for me in the past pigeons chose their own mates and build nests all over the place, corridors, corners even one or two in nest boxes absolutely haphazard.I know this is frowned upon by serious fanciers but the doos seem happy and so am I."
