Well I have lived here for a little over 6 year's now.We got introduced to our neighbor's dog trixie a couple month's after We moved in.She is an Aust. Shepard.The owner had gotten her as a pup apparently and had her a couple year's before We got here.She started coming down and was a great dog.We had pig's and a few chicken's at first and a few duck's.Over the years she has been sooooo awesome around all of the bird's.She basicaly stay's all day summer until cold month's during day and has been around all the brooder's chick's buyer's duckling's everything.She goe's with me to feed goes in the coops lay's on the porch just hang's out.But this past weekend I had a silkie that hatched out 6 on the ground chicks a couple week's ago im brooding one because it was a late hatcher. Anyway the mama has already gotten the babie's coming from her coop to outside.We heard peeppin loud Sat. and thought maybe one of the young had gotten away from mama yep right to trix! She had slobe's all over it luckily DH got it in time!.Today I graduated 8 chick's 2 silks and 6 OEGB's.I went out about 2pm and heard loud peeping again so I figured one of the hen's babie's had gotten mis routed again.It was in the alleyway between the coop's and I was in the coop pen area.Trixie was right on the peep and shot out like lightning.Before I got to back yard .The little black silkie had found a very small hole in that pen and got out. There wasnt much left but eye's and fur!I was never so angry!.Why is she doing this now? I hate to think she will turn into a bird killer she has been here with literaly Hundred's of them over the year's.
