Perhaps quality is better than quantity! If you really feel the need to feed I would go for better quality food less often. Otherwise I would look to plant things in the garden that provide natural food sources.
How do you know the 'plump pigeons' are not pigging out on your H.W. Nevill's bread? Do you want to attract pigeons? Most consider them a nuisance.
s, I will go for quality from now on, Cutie!
Dont think any of the birds get much of a chance to pig out, they all come down at the same time and mingle. There has only ever been four pigeons at most so they are no nuisance.
