Every since I got Molly I have noticed the difference in the colouring of thier legs and feet, Blue has greyish, bluish legs and feet while Molly has pink feet. Is this due to health reasons or the fact that they are different ages or genders???

Some of my birds have grey feet and others pink too. I don't believe it has anything to do with age, gender or health, but I'm not 100% sure why it happens but I think it has something to do with their feather colours. I'll look into or I'm sure others will have an answer for you!

Depends on the mutation of the budgie

Agree, depends on mutation of the bird and colour
