Hi all, I'm new here

I've had a few chickens for the last year or so, ISA brown layers but I fancy getting a purebreed again.
I used to keep, breed and show bantams as a youngster but had to give it up once I started my 20+ year journey in the poultry industry.
Anyway, I went to look for some recently and was completely bowled over by the prices these things are making now!
I've seen £30-£50 per bird being asked for some!
Now I have no doubt this may be current market value but its only a chicken!

So, does anyone know of any purebreeds for sale at reasonable prices? (for a tight Scotsman)
I'm looking mainly at egg production, so would probably lean towards black or white Leghorns but i'm not too fussy.
Still have the old incubator, so even if I can get a trio I could breed my own.
Any suggestions?
