As an ex breeder of Quail I have never come across Italian quail,but all Quail need the same care .
Their pen should be no higher than 2ft.and as long and as wide as you want and a cover over part of the pen also a place to hide,such as an upturned box or similar.
Quail when startled have a horrible habit of taking off like a "Harrier jet" ,"straight up"and can do some damage,even break their necks.
Feeding, Wheat Small seed ,Poultry pellets,crushed smaller ,last but not least Water.
When breeding any large water container should be removed and changed,to a tubular drinker as used in bird cages,the reason Quail chicks for some unknown reason are -attracted to water when hatching and a large container is where they will drown.
Their down also becomes waterlogged and they will die from chilling.
