We got chickens last May 8th. We have been so very lucky to have not lost even one. Yesterday we woke up to a dead cochin hen. The other two in the pen and coop were okay. Something got in over the top....yes, it is covered but the wire is welded but large squares. I went to town and bought smaller wire to put over what is there. I moved the remaining cochins to the chicken tractor that is VERY secure. They spent a safe night. This morning there was a loss in the Barred Rock coop. I battoned down all the hatches...even put cinder blocks in front of the pop doors. Something dug in.....we are so rocky it had to have taken them forever. I heard the noise and my husband was not home. My nephew drove by a few minutes later...while I was still hanging out the bedroom window and I called him to come go out there with me. We did not see anything and his dog ran around all the coops but did not get excited about anything. I just had a really bad feeling. All this time with chickens outside my bedroom window....I knew the noise I was hearing was just not right. But I felt good that the pop doors were closed and the cochins were safe in the tractor. So I am saying.....everyone go out and take another look. This was the only place on the coop that was not dug down in the ground. Today that gets fixed. It just makes you sick. And this is the time of year...trust me, they are out!!!
