I have big breeding plans and know that to do this I have to be careful about what I keep and what to cull. I am sure this is already explained in detail but I cannot find the info so my question is... How do you cull your chicks? How do you cull older birds? I mean..how exactly. Drowning? Cracking necks? Chopping off head? oh I think I feel sick already..... Is there a humane way to do it with the least horrible feeling? Any input?
