i'm busy planning for next years breeding groups and as it will be my first year breeding araucanas, im looking for a little advice. i have 6 rumpless hens (2 with tufts 2 without) 2 'tarwe' coloured (sorry dont know the english name for the colour..i think perhaps wheaton?) 1 blue 3 black and 7 with tails (one with tufts) 4 black 2 tarwe 1 blue i have three roosters, 1 black with gold neck (rumpless) 1 blue/red/grey (with tail) 1 that im not sure of the colour yet, i pick him up tonight and have to chose out of 6 (blue, white or black) so im guessing i can make 3 groups. but which hens to which roo's? which will make nice coloured offspring? ive heard i shouldnt put the rumpless roo with the rumpless hens as i'll get deformed chickens? what causes this?
