Centrarchid, thanks for the advice, its always good to be reminded of that fact.
My chickens have the run of about 1/2 an acre that has a lot of cover for the birds and the coop is very secure - well at least at night when it is all closed up. I did have a Red Tail hawk get into the coop through the pop door a few days back, I don't know how long it was in there. When I got home from work I heard a strange sound comming from the coop and when I opened the door I had a hawk in my face. The hawk was trying to get out, but could not find a way and was just flying around in the coop. My coop is 8x12x8 soon to be 12x16x8. There were 3 girls in the nest boxes, Tweety and her babies were in a little cage I setup on the floor of the coop and another one of the hens had got in there with her to hide from the hawk. I have never seen my chicken so still and big eyed as that.
I did not lose any then either and I know the chickens were lucky. I have a plastic bag tied to the pop door now so the wind kind of moves it around and that seems to keep the hawks away from the door. I need to get some ScareHawks put out as soon as I have time. I have not lost a chicken to a hawk or any other chicken eating critter for two years now so I must be doing something right and the chickens are very good at duck and cover.
7L Farm, I could never sell Tweety. She's my babie raiser. She has hatched and raise 14 chicks this year. She's just about 1 1/2 years old so she will be with me for a long time. Well back to work.
