Would be very grateful for any advice on where to start with a major problem.
Our 20 week old lab pup today gained access to our hens and killed one. We initially thought a fox had done it because the head was ripped off, chest opened and everything inside eaten. However, after locking the other hens in for most of the day I let them out late afternoon when I was outside to keep an eye. For unrelated reasons, the pup had been in her run most of the day so I let her out simultaneously. Took my eye off for 5 mins and in that time, the pup had gone into next door's field from where she must have found somewhere to access our property where the hens are. She can't get in from this end because it has been fortified with netting. Anyway, heard a rumpus, ran like a mad woman and rescued another hen from her clutches.
Now to give the pup credit, when I called her name and off, leave, come she came to me. Ran back after the hen once but came again when I called her and followed me back to the house. The hen is fine.
Clearly, the first thing we will do is make sure the hens are safely enclosed (as we had thought they were - sigh).
Where do we start with the pup? Is it back to lots of supervised, on lead walks around the cooks? I worry now that she's killed one, tried to kill another and, of course, she's a lab whose instinct is to kill. We're obviously willing to put in whatever work is needed to try and sort this out.
Advice very much appreciated if you've got this far!
