My first broody hen !!! (with photos) Update! I set her up in the coop

I have a partridge cochin hen (Foxy) who started to act broody. She sat on few eggs today all day long in the nesting box, and when I tried to touch her she made sounds like she is about to eat me. In the evening however she went to sleep inside the coop with the rest of the chickens and left the eggs. There is an egg box attached to the coop with access from inside, but for some reason my hens prefer to use the outside egg box for laying their eggs. If I want to let this hen going broody what do I need to do?

First, how can I make sure that the eggs she is seating on are fertile? (I have a rooster that is a little clumsy and not all my hens have fertile eggs)
Do hens have to stay on the eggs all the time?
How long is the brooding period until hatching?
How long they can be off the eggs to eat and do their business without “loosing” the eggs?
If she starts to be broody on the outside egg box and I move the eggs in the inside box will she still stay on the eggs if I move or touch them?
If I want to save few eggs from the same hen, can I put them in the refrigerator for few days until I have enough for hatching? Will the eggs still be good for hatching, or do I have to keep them at room temperature?
Will a broody chicken remain on the eggs if other chickens are around her? (inside the coop)
Do I need to separate the hen from the rest of the group for the brooding period?
Will a chicken still lay eggs during the brooding period or will she stop?
Do roosters take turn on seating on the eggs?
For the past 2 weeks George has been watching Foxy while she lays her eggs. He usually seats in front of her nesting box until she is done. I noticed sometimes he gets in the nesting box and makes this clutching sound until another young laying hen gets in the box with him and then he leaves the nest. Almost like he is trying to show the hen where to lay her egg. (I got one of this times on video. The Mille Fleur hen in this video give me her first egg next day)

I don’t know what to make out of this behavior, I don’t know if chickens have that instinct of sharing the broody duty or is just my rooster a very strange rooster. On the other hand this is the same rooster who use to mount my silkie rooster witch use to be his favorite up until three weeks ago, when I sold the silkie. Now his favorite is Foxy and he follows her everywhere like a shadow.
This video is with Foxy, before she went broody, and she use to be very dramatic every time she had to lay an egg.

Thank you all for your kind comments.

 

After several days of observing her, I finally decided to let her go broody. First I had to figure out where is the best place to set her up. The outside nesting box (witch she preferred) was not a good choice because at night she wanted to go inside the coop with the other chickens. So, I made a temporary separations inside the coop and put her there with ten eggs that I gather in two days. At first when I moved her she tryed to get back in the original nest (outside box), but on my third try she finaly settled in the new nest. She has been there all night, and so far, all day today (yesterday she was in the outside nest). She went out only once today for few minutes to eat and do her business. I put some food and water close to her and I even got her some special treats “Happy Hens dry meal worms”. This is my first broody experience and I hope everything will go well. I feel bad for the poor girl,because she has already lost some weight just from the past few days keep trying to sit on eggs and not eating enough. I got some food supplements that I mixed with her scratch grain for some extra proteins and vitamins. I hand feed her few times today, because I am worry about her not eating enough.
I know for sure from witch hen are 7 out of 10 eggs and the other three I have them with a question mark. I marked all eggs with a number, and I wrote in my note book each number to what hen belongs to.
This are the eggs I put in:
2 Buff Brahma (one of them is show quality hen) fertile by my Buff Brahma rooster
1 Light Brahma (fertile by my Buff Brahma rooster)
1 blue splash cochin (fertile by Buff Brahma or silver duckwing rooster)
1 silver lace cochin ( show quality) (don’t know if her eggs are fertile)
1 Golden Seabright (fertile by silver duckwing rooster)
1 White Mille Fleur (mix) fertile by Buff Brahma or silver duckwing rooster
3 not sure eggs but one I believe is an OE Mille Fleur (fertile by Buff Brahma or silver duckwing rooster)

I'm hoping that everything will go well and my Foxy will be a mommy with

This is the new set up. I have another baby gate for the front door during day, that I took down for photos.







I love this rooster every day more. I love how concern he is about the hens to be happy. When the girls get in a fight he always gets in the middle. He’s very sweet with me, never show any aggression toward humans, but he does chase the little silver duckwing rooster every time that one tries to mount one of his girls.

 

I have a broody hen on her second day (my first broody). I got ten eggs under her, and I am curious to know what should I expect if they all or some of the eggs will hatch.
{A} What do I get if my Buff Brahma rooster is mix with:
1) Blue splash Cochin 2) Partridge Cochin 3) Silver lace Cochin 4) Golden Seabright
5) OE Mille Fleur
6) white mix Mille Fleur
7) Light Brahma

{B} What do I get if my silver duckwing rooster is mix with:
1) Blue splash Cochin 2) Partridge Cochin bantam
3) Silver lace Cochin 4) Golden Seabright
5) OE Mille Fleur
6) white mix Mille Fleur
7) Light Brahma
8) Buff brahma

Thank you.
