Aahh, if you are in it for the eggs I would go for a bigger bird. Banties lay rather small ones.
I tolerate my escape artists as they lay fabby blue/green eggs and have cute pompoms atop their bonces.
My most prolific layer is a 3 yr old Marran coucou (brown and white stripes) that I thought would lay dark brown but lays normal egg colour - she was a couple of quid when I got some pol, they said she wouldn't lay many, she's only missed 2 days in 5 weeks and lays a good 70g.
My coral nick (white bird) lays white
my ambers (white base one with few and one with many gingery freckles) lay pale eggs/normal - nice friendly nosy chickens that like to join in activities!
My bluebelle lays mid - dark brown
My speckledy lays a v.small speckledy egg
My Daisybelle/black pearl lays a mid brown with a white speckle.
I love being able to tell who produced which egg - apart from the 2 blue layers, the 2 ambers lay diff shape/size.
Luckily we are nearing full capacity in out hen house or I would continue to get them!
Find a supplier with a selection and go pick some pretty ones, modern hybrids are bred to produce high yeild - better than pure bred birds.
The only downside is in winter it will not be so much fun, not had chooks through the cold/wet yet but have 2 ponies so know what it is like.
