Hi,
Im currently looking for a pair of quakers, male and a female to enter my newly built aviary.
Iv found a place to buy from but they don't offer dna sex on the quakers, i was told this is because they can determine the sex from an eye examination, iv never heard of this so im wondering if this is rubbish, a way of doing so but not as effective as dna or is this an old understanding of how to determine the sex that is outdated.
Thanks
