Hi Jimmy,
Don't know about you but lots of things seem to have changed in their colour,strength and look, ( me too ) LOL.
I have though noticed that WHATEVER we give our birds from Electrolytes to Multivitimins, whenever these are added to the water the birds are never keen to drink em'.
Talking about changes, even my beloved Creosote has lost it's smell, not too sure now if it has the same effect on loft insects/mites.
