Chicks due to hatch in 7 days ...any tips appreciated ;0)

Hi, I am new here. I have 3 adult chickens. A Suffolk who became broody and a friend gave me 5 eggs for her to sit on. It is nine days and I am seeing veins and moving little chooks in 4 o 5 eggs, one is a green egg which is dark to candle through.
I have never raised chickens so any advice will be appreciated.
I also have an Iza Brown and an Australorpe adults in a large pen with a tin shed where nesting boxes and roosts are. They are friendly and follow me around. Unfortunately the Suffolk is not so attached to me but is a bit better since brooding.

I have the Suffolk in a dog kennel cage in the shed sitting on the eggs in a small box with sugarcane mulch under them. There is a small bowl of water and a bit of food in the cage and I have the cage partially covered with a towel. She comes out twice a day to walk around, scratch and eat and returns after 5 mins to sit on her eggs again.
I have been keeping her and the eggs separated from the other chooks and also to keep visiting mice and a Diamond Python snake who visits my pen and occasionally eats the mice and steals eggs away from them.

I have a larger cage I can put the chickens in when they hatch.
Should I keep the hen in with them. Any suggestions on food.
I am on the south coast of NSW Australia...Tapitallee and it is springtime here. 12 degree nights and 18-20 daytime. Wedge-tail Eagles and Grey Goshawks are a problem for free ranging so my girls only get outside the large pen when I am home to watch them.

 

Thanks Sumi. Just three more days to see if the eggs begin to hatch. I will keep you posted.

 

Three of the five eggs have hatched. Three little beauties. Day 2 and they are cuddling under a very protective mother hen.
