No l didn't see, but I think that you have got some good suggestions on the original thread. You never said if you add a new chicken to the flock. Do you quarantine? Do you keep a closed flock stragety? The worst thing you can do, IMHO, is to have a flock that is in a constant change, I always use the "all in all out" stragety and never have a multi age flock.I breed them as dual purpos chicken. First of all, I was looking forward to have healthy chicken. In the second place it would be gratifying if they had good productivity in terms of dual purpos.
Currently I have all generations, but the focus now on which are 1 month old and which are 2 to 10 days old.
By the way, have you seen such a thing in your region? which pathogens do that?
