Hi all
Thankyou to everyone who has replied wow.
I learnt a while ago that a canary can be either a hard or soft feather type. It was a real issue for me and I had to work out what I had in the avairy. I had no clue about either and done extensive research.
Thankfully Charlie's parents is a hard x soft which is the perfect combination by breeding standards across the board. However as many have said it is safe for a soft x soft should the offspring not be bred with a soft feather..this is then called double buffing and leads to the feather being increasingly softer. 1-2 generations of double buffing is ok but then a hard x soft or soft x hard is required to bring the feather back into condition.
There is alot of terminology that basically means the same thing.
Soft feather could also be called =
buff, non-intensive, frosted, schimmel & mealy
Hard feather could also be called =
Yellow (not the colour), intensive, non-frosted & jonque.
I actually prefer the terms intensive and non-intensive.
A hard x hard does cause the lethal factor of 25% of the clutch, unhatched eggs and death of hatched chicks. The lethal factor also occurs by dominant white x dominant white. Genetics is a mine field but very interesting.
