These are 66% het hypo, meaning you have a 66% chance of these being het hypos instead of normals. They are not visually different from a normal looking redfoot. Sometimes its impossible to visually tell the difference between a het and normal redfoot. But sometimes their colors are so much brighter its recognizable, and these in particular have some orange in them, making them look a little different than your average redfoot.
below is the break down of hets and hypos to help you better understand.
Hypo x Normal = all 100% Hets
Hypo x Het = 1/2 Hypos 1/2 100% Hets
Het x Normal = 1/2 normals 1/2 100% Hets (this gets you all 50% Hets because visually you cant distinguish normals from Hets so you have to sell them all as 50% Hets. However, they are either 100% Het or Normal, you just don’t know which is which)
Het x Het = 1/4 Hypos 1/4 normals 2/4 100% Hets (in this case, 3/4 are NOT Hypos. Out of those 3, 2/3 are 100% Het and 1/3 are Normals, so this yields all 66% Hets because again, you don’t know which normal looking animals is a Het and what normal looking animal is a Normal.
If you bought babies from Het x Het, they are 66% Hets. 2/3 of yours are 100% Het and 1/3 are expensive normals.
