I put 53 two week old coturnix in a dog carrier overnight. They were in a shed that could use more ventilation so we left the door cracked about an inch at the bottom. The wire on the cage was 1 inch, they were only going to be in it one night because we had to finish putting the door on the new cage and they were too big for the brooder. I went up to put them in the new pen and 12 were dead. They all had their necks broken and a few had the heads ripped off. Something tried to dig into my chicken pen, but it didn't get in. I think a raccoon did this. Am I right? Should I keep them in the garage until I wrap wire around the legs of the cage? Thanks
