easiest breed to sex at birth?

hi all,

im hoping to breed some more chicks when things start to warm up (dont tell my wife!) and i was wondering which breeds are easiest to sex at birth, id prefer good layers and/or meat birds?
i like welsummers, sussex, are there any ways of telling at birth which sex they are?

 

chookiechook:-you say sussex can be colour sexed ie light hens buff cockerels
is this the combs you are talking about ?
i have 4 9wk old light sussex bantams and they all look the same to me

The way it works is that if you have silver/white hens and a buff cockerel then the chicks hatch out different colours ..... sorry, cant remember with any accuracy what the colours are

Why not post a pic of your birds and we will all have a guess

im glad that cream legbars are easy to sex, ive got 4 hens so i will get a cockerel to go with them.
all my laying hens are still laying at the moment and its been freezing up here in the north west!

if i did that what do the chicks come out like and what are the differences between the male and females?
