RE: Bantam Cochins Is is possible to start breeding your pullets and cockerels at too early an age? Basically, if you start breeding at too young an age, can it affect the growth rate, health, quality, etc. of the chicks to be hatched? Will I notice any difference with the chicks if I start breeding as soon as possible, say at 6 - 7 months, or is it better to wait until they are 8 - 9 months old, or does it matter at all? Hope this makes sense!
