Hi Maurizio
Do you realise that we have a sister group called Talkcockatiels - see the bottom of the column on the left side of the page.
There will obviously be more people with cockatiel experience in that group - So, I suggest you join that group to get answers to both these and future questions.
Wishing you well with the purchase of your cockatiels. I hope they'll quickly settle in to their new home (The red eyes are perfectly normal, it's just a different mutation.)
