Good afternoon, I have just joined and this is my first topic. Please be gentle with me. I have kept hens for a number of years and have had great pleasure as well as a plentiful supply of eggs. I am now going to bring on some birds for the table. I want to have up to 10 hens at a time so no problem there. Then when they have been despatched I would like to put a couple of turkeys in. I have read that black head could be a problem. I have not come across this before, so does that mean I can only keep one or the other, or would a good clean which I would do anyway, allow one to follow the other. Any advice would be gratefully accepted. Thanks everyone, Paul.
