We will overcome.
I will have some pics taken of the survivors later today. Sadly the chicks were scheduled to move to a coop today. All the coops are cat proof.
The brooder had a small hole in the plastic mesh where a an oversided brooder light had melted the plastic mesh.
The cat must have got in through the small gap between the wall and the tin roof.
Tonight we shall have a special treat for cats set up in several locations with the dogs tied up.
