I just checked my chickens tonight and as I walked up to the gate it was moved from the bottom out. We have a piece of plastic hooked from one way and have a chainlink gate leaning up against it the other way to block the bottom opening. I didn't think to much into it till I got walking around and seen part of a wing, then got walking around more and found the chicken. She tried to squeeze through a large crack in the concrete on part of an old garage. I got my FIL and we started counting the chickens and have 3 missing. Something ripped the wing off pretty good since there was a big chunk missing. He thought either a raccoon, skunk, or the neighbors dog. Our dogs usually bark crazily if their is a skunk or raccoon and the dead chicken and 2 of the missing ones were fast. I don't think a raccoon or skunk could of moved the gate and the rest of the fence didn't have any spots that I could see for something to get under at. Also with their being 4 chickens involved I'm assuming it is the dog. My SIL's dog has been in heat and the only other dog that comes down here has been fixed and been coming down for years without attacking any animals. This other dog is a black lab that the neighbors have only had for maybe a few months. Since her dog was in heat it kept coming down here since we live probably two blocks worth of land from the village. My FIL did run him out of our chicken area when he went in to feed them since the dog came in behind him. We have notified the owners of the dog coming down here cause of the other dog in heat and he was knocking our door open and coming into the house. One of the days my MIL drove down cause she seen the dog around earlier and when she got to the owner's house they said it must of been a different dog cause the dog was there but it had the same bright orange collar on it. We don't know what to do since the owners most likely won't keep the dog in their yard and the family has kids that play with it. One of my favorite roosters that just was recovering from a turkey trying to bred it and hurt him is missing. He was one that I planned on taking with me when my husband and me get our own place along with the hen. They are both WLR Cornish Bantams. Another reason we think it might be the dog was cause our dogs don't bark at him. There was a skunk around a while back which there usually is but I don't think a skunk could of gotten a hold of 4 chickens in one night with the chickens being fast. The missing area on the bird was a huge spot that would of had to happen very quick for the bird to of gotten into the crack before it died since the animal couldn't of gotten to the area where it was in the crack. Does anyone have any suggestions on what to do? Our dogs are allowed to run free since it is a farm so I'm worried about use calling them or the shelter and them turn us in for our dogs about something or them come up missing. I don't want to see anymore of my chickens coming up missing or the turkeys since one just started nesting.
