Thank you all for your encouragement
Alan as 50% of the chicks will be cockerels at what age do they start crowing, reason being Liverpool City Council do not allow any cockerels on any of there Allotment sites, So I am afraid its Cock-a-leekie soup for them

Also am I right in thinking that if I wanted to start breeding my own stock, I would be better getting a Cockerel that is not related so to speak?
Chantal You are right I am worrying unnecessarily, but I hate it "the not knowing bit " and yes it does come across as rather complicated but with everyone's help I am sure it will be a success
Diane Thank you so much for this advice, The first time I read it I thought hells teeth I was worried about frying them and you tell me I might Drown the beggars

Well I have re-read the user manual and your advice and I am feeling a little more confident (just a little not a lot)
As I am incubating Light Sussex Large Fowl Will it make a difference to the advice you have given

I am I right that you do not put any water at all in the incubator at the start ? or do you try to maintain a 50% humidity from the start
I have to get this right as Tatty Head (Dear Wife) has told Nieces and Nephews that I am making chickens in a box in the kitchen So No Pressure Then
Thanks Again for all your help
Kevin
