Layers Pellets with Flubenvet....

[ssdcc01]

Hi, I am in the process of worming my chickens using Marriages layers pellets with Flubenvet, the bag states that the contents will be out of date come the 3rd July, I have just bought the bag and would like to know if anyone can inform me if the Flubenvet will last longer than this. I only have two chickens so they will not go through a 10kg bag...Please help.. Thanks in advance
