Unknown Grub can anyone identify please?

Hi All,
I know this is a bit off the subject of Poultry etc but as you are a knowledgeable lot i thought the may be able to identify this horrible Grub i found in my bedroom it's the second one i have found between the carpet and skirting board I promise i will post a pic of my new cheeky happy Novo Brown hens i have recently bought any advice on the Grub much appreciated as i cannot find a pic of it anywhere 

I think that it looks like a carpet moth grub. If it is you need to do something about it as they would ruin your carpets. 

Hi and thanks for the suggestion but i think not as this grub is around 20mm long with a black dot on it's rear if that helps 

Thank you and yes they are the pics taken are on the day i bought them and put them in my run they instantly settled in very friendly and chatty they are to and very inquisitive best hens i have had so far 

Did you feed the said grub to the chooks 

Mystery solved im sure it's a Weevil Grub of some sort that has come from our log burning stove logs which we keep in a cupboard under the stairs
