Confused about baby's colour
I paired up 2 sky blue budgies and 1 of their babies looks like it is going to be cobalt blue. When put next to its sibling and parents it is defanitly a darker blue. Why is this I thought Sky Blues would only produce sky blue babies.
Mum is a sky blue sf yellow face 1 sf spangle
Dad is a sky blue normal split for ino
Their babies have ended up being
Baby 1 same as mum
Baby 2 what looks like cobalt blue
Baby 3 creamino
Baby 4 is going to be blue ( feathers just starting to come through)
I have attached photo of baby in question. Would only allow me to attach 1 photo but do have another of his/her front if needed.
