circuit designing

pls dont accept my bid unless clarifed I have to make a chicken coop, which it will be automatilcily im going to design a light sensor which it detect the sunrise, when the sunrise comes the door will open for the chicken to go out and fed them selves, and when the sunset comes the door will close. the food should be in a serten level. also the water. all of that will be working by a rechargable battery, which it will be charged by a solar. what you think? As per i think there is 2 issue so you can keep 2 option 1) when weather changes the door will automatically shut down , so we can keep a timer for it according to my country ( we can change the timer manually for this ) 2) keep a senser were it opens the door when sunrise and close when sunsets When water level and food level lowers something has to detect it and put food into this \can you do >??
