This is 100% stupidity and my fault. I had a doctors appoiment at 6 and was running late. I let my 2 big ones wander around and I left the spare back room window open in case they don't go in there coop by night time. Turns out we had a nasty storm in Houston. Again my fault I should of locked them up. I came home and went straight to bed. I woke up to feed and check up on them and one is missing. Her partner the rooster is also worried and searching around the backyard for her. I took my bike out and searched the neighborhood still no luck. I am assuming the neighbors cat got lucky. I looked around for sign of struggle and feathers no luck. Wet chickens can't fly so I know she didn't jump the fence and every hole is covered so she can't go to the neighbors yard. I am not going to give up on the search yet, I alerted the kids around the neighborhood. But I learned my lesson.
