Hi All and thank you very much for your responses.
I don't know how to upload a photo but have changed my avatar to show Sandy.
Update: We let chooks out this morning. Sandy still not eating. Put a separate bowl at the end of the pen... she ate! Then changed height of the food container.... she ate. I think we sadly put this at the wrong height. anyway she ate and drank, didn't sit down and wasn't lethargic.
Then Keira and Freya laid their eggs in the coop. About 45 mins later Sandy decided to go up to the coop.. She sat for about 20 mins. Connie was desperate to lay. She went up but Sandy wouldn't have any of it. Anyway to cut a long story short (at this stage lol) Sandy laid an egg and was sitting on it. We took her out and placed her in the pen, and took the egg. She went back in and sat on Connie. We removed her again. Connie laid her egg and went down to the pen.
Sandy then went back in the pen. We researched again and decided she must be broody. We shut the coop door, having got her out again, but she climbed the ladders at least four times. She then started attacking the other girls aggressively. We opened the door, let her go in and then after a while went out to buy the materials to make a separate coop with wire so that her "undercarriage could be cooled".
On our return and to our surprise she was down in the pen with the others and acting normally!!! No aggression... you would think we had imagined all this. However she did sit for a whiile and puffed up. We still think she's broody... what do you think?
Once again thank you all for your input and care. I've decided to write a blog "KFC and The Colonel" (Keira, Freya, Connie and Sandy. Purely for my amusement and a diary for our venture forward... here's hoping i can figure out how to!
Oh: breed: she's a hybrid called Miss Pepperpot... a cross between Rhode Island Red and Maran cross) as is Freya. Keira and Connie are Gingernut Rangers ... a cross between Rhode Island Red and Light Sussex Cross.
