Today is a sad day for us. We have lost a chick already. One of our 12 week old Red Stars. We have been working on making their coop and run ready for them, and thought it was pretty good. We were having issues with the bottom of the fence being too open and them getting out, we plan to put a 1x6 across to keep them in. But, it hasn't been done yet. I was too easygoing, trusting them to be okay all the time. I have seen a hawk flying over for the past couple of days, but I don't have any experience with hawks. We left the girls out for about 2 hours today while we were away for the house. We came home and they were outside the run. We cooped them, and my daughter counted them. She only counted 5 big girls instead of 6, and my dh confirmed. I wandered all over our yard, checked the field next door and the neighbor's yard. Then, I found a little pile of clumps of feathers. I believe a hawk got her. I plan to keep the others cooped for the next week at least while we fix the bottom of the run and either string fishing line or chicken net over the top. I'm so sad, and so is my daughter. It's a lesson I wish we didn't have to learn this way. I guess I was just too optimistic that they could be carefree free rangers when they wanted. Now, I have to figure out how to keep them cool while in the coop in this weather. It's around 85-90 each day. I have two windows and two vents in the coop, I freeze gallon jugs of water and hope that will help "air condition" them, and I plan to run a fan out to them. Does this sound good?
