Llouella has been mentioned on a previous thread regarding i'll young birds. Last year a neighbour purchased a team of youngsters from there and within a couple of days they started to die, fortunatly they were isolated from the main loft, after a week of daily deaths the balance were sent back and money refunded.
He's just had a letter asking for him to check his birds as they beleive they may have transfered a wrong ring to him, they have clearly resold one of the sick birds that he returned last year to somebody for stock!
