Which matures faster? or same

[quailmale]

Do "Jumbo Coturnix" grow out faster than the infamous "Texas A&M's", I bought some of both and the "Browns" are 1/3 to 1/2 larger than the "A & M's at the same age. By what I have the answer is yes but I would like to know in general is there a differance for real ?

Thanks

What I have found is that the whites do grow a bit slower but get as big. They need to be in different pens as the browns are pigs.
