The greencheeks, IMO, should be a year old if not older, before they breed. If they are not mature enough, they may not raise their chicks right... abandoning them or killing them.
If you could get in contact with the man you bought the first pair from, you could ask him (if he recalls) what the mutation of the chicks are... although I'd be a bit worried if these two are related if you got them from the same person.
Since cinnamon and yellowside are both sex-linked mutations, the only way to get a cinnamon yellowside (pineapple) would be if the female was a visual cinnamon yellowside, and the male either was a visual (of one or both mutations) or if he was split. To get a male split to this mutation, you could pair a female cinnamon yellowside with a normal male. To put into more simpler terms....
Male normal x Female cinnamon yellowside
Male offspring
Normal split cinnamon yellowside
Female offspring
normals
Male cinnamon yellowside x Female Normal
Male offspring
Normal split yellowside
Normal split cinnamon
Normal split cinnamon yellowside
Female offspring
Cinnamon
Normal
Yellowside
Cinnamon yellowside
Male normal split cinnamon yellowside x Female cinnamon yellowside
Male offspring
Cinnamon split yellowside
Yellowside split cinnamon
Normal split cinnamon yellowside
Cinnamon yellowside
Female offspring
Cinnamon
Normal
Yellowside
Cinnamon Yellowside
Male cinnamon yellowside x Female Cinnamon yellowside
All offspring cinnamon yellowside
And of course there are more possible pairings... such as a cinnamon male split yellowside, or a yellowside split cinnamon, pairing with a normal female, a cinnamon female, a yellowside female, etc. Which you can experiment with the calculator. However, in short, there's no possible way to get male cinnamon yellowsides if you have a normal female (no matter what she could be split to).
Now, for a turqoise, since we are only speaking of one mutation and not two, it's quite a bit more easy to do...
Male normal x Female Turqoise
Male offspring
Normal split turquoise
Female offspring
Normal split turquoise
Male turquoise x Female Normal
Male offspring
Normal split turquoise
Female offspring
Normal split turquoise
Male normal split turquoise x Female turquoise
Male offspring
Normal split turquoise
Turquoise
Female offspring
Normal split turquoise
Turquoise
Male normal x Female normal split turquoise
Male offspring
Normal split turquoise
Turquoise
Female offspring
Normal split turquoise
Turquoise
Male turquoise x Female turquoise
All offspring turquoise
So, if you have a normal hen split turquoise, if the male was also split turquoise or was a visual, you'd be able to get turquoise males... however, if only one parent carried the gene you will not get any turquoise offspring, only some that are split.
Double split means that the male is split to two mutations. The pineapple mutation is not ONE mutation, but TWO mutations. It is a combination of cinnamon and yellowside. If she's bred this pair before, and has gotten female pineapples (cinnamon yellowside), then she is correct in saying the male is double split. So if the male is split cinnamon yellowside, and the female is a visual yellowside, this would be the results...
Male normal split cinnamon yellowside x Female yellowside
Male offspring
Yellowside split cinnamon
Normal split cinnamon yellowside
Normal split yellowside
Yellowside
Female offspring

Once you understand the basics, it's pretty simple!
Sex-Linked Mutations (cinnamon & yellowside)
To first understand this, you need to understand that males have X, X chromosomes, and females have X, Y chromosomes (the opposite of humans). A sex linked mutation can ONLY be carried on the X chromosome, thus in females it acts like a dominant gene and they are always visuals. In males, the sex-linked mutations act as a recessive gene, in that in order to be visual they must have the gene on both chromosomse.
Recessive Mutations (turqoise & pied)
In order to produce visual recessive offspring, both parents must cary the gene either visually or split. Both males and females can be split for recessive genes. The offspring must obtain the recessive gene from both parents in order to be visual. If they only obtain the recessive gene from one parent then they will be split.
Dominant Mutations (grey and misty)
Dominant mutations work in the fact that only one parent needs the gene in order to pass it off to their offspring as visuals. They cannot be split for dominant mutations, so it's either they have it visually or they don't have it at all. If a bird only has one dominant gene, they are called single-factored. If the bird has two dominant genes (of the same type), they are called double-factored and their colors are more pronounced than a single factor.
