there are 2 standard methods used for DNA detection

1) Blood  usually obtained by clipping a claw short so that the blod supply is breached . A drop is then put onto an absorbant paper/cards which are the put into a plastic bag

2)  Feathers  these are normally taken from the breast , although if there is a problem I take some from the rump . Also if there is a question about getting a DNA sample I also check with a hand lens . Feathers quills with no DNA  will taper to the tip , but those with DNA material will have a slight swelling just before the tip . The feathers should be handled carefully to avoid contamination & put into  a plastic sample bag  ( 1 per bird )

Some firms use both methods others 1 . & I'm not sure which Sexado use  but you need to contact them for sample kits

With Sexado you print off forms to which you apply blood or add feathers. Most important of all is avoiding cross contaminating. They did tell me that blood samples are better due to feathers not always having the needed DNA as Colin brought out. Jan

I post mine standard class, and the site indicates when the sample has been received, mine normally take no more than 3 days.
