I have winter extensions for the chickens for when we have 70mph winds and snow (we live in the highlands of Scotland) - we've had both recently, however I thought the rats were getting to the plastic as they had started to be eaten away. The coop has been there for as long as our two wyandottes have which has been nearly a year. Today I just spotted the wyandottes eating the plastic so I removed it and in the process one of them ran up, snatched a very large bit and proceeded to eat it before I could grab it from her. There is no way any vet near us will attempt an operation on a chicken, they find it ridiculous when I insist on them being treated for anything and know virtually nothing about them. Will she die? is there anything I can do? she's walking about fine at the moment but it won't have affected her yet. Any help would be appreciated! They are usually very clever! I don't know why they have started to doing this.
