Would all the chicks from a Creamino female and Normal male be Normal chicks split to Creamino

No, the females wouldn't be split to cream. Only the males can be split to cream.

Quoted from the website:
Creamino plumage coloration, as well as a fawn, is sex-linked recessive trait. Birds that have this coloration carry ino mutation in a Z sex-chromosome that is usually referred to as “cream-ino". This mutation will visually appear in females because no counterpart gene is present to suppress it. Normal shafttail males Z+Zino are described as being split to ino, a.k.a. split to creamino. Again, if a male Z+Zino is in pair with the normal female, we will obtain only female mutants ZinoW; the other birds will be normal males Z+Z+ and normal females Z+W or normal males split to creamino Z+Zino, Table 5. With a male split to ino mutation ZinoZ+ and a creamino female ZinoW we will obtain creamino males ZinoZino and creamino females ZinoW, and also normal males carrying mutation ZinoZ+, and normal females Z+W, Table 6. With a creamino parent male ZinoZino and a normal parent female Z+W, all offspring males will be normal split to creamino ZinoZ+, and all offspring females will be creamino ZinoW, Table 7. With a creamino male ZinoZino and the same mutant female ZinoW, we will obtain 100% creamino offspring Table 8.
