I have never culled a chicken, but apparently I have a silkie with Marek's disease. I can't cull her but my husband is willing. What is the best way to put this chicken out of all her suffering? I have already got the advice from a chicken doctor and we have tried everything to improve her progress and nothing worked. She is at the point now where she's just suffering, she is flopping around with absolutely no use or control of her legs. She's bleeding from her vent and I just can't see her suffer any longer. She's been sick for about 3 weeks and during this time she has just gotten worst and worst.. So I have come to the decision which i really didn't want to make but decided is was time... So i'm wonder what's the best way?
