i had a silkie rooster who i used to have until he crowed to much and was rehoused at a little community farm. I go their every 2 or 3 weeks to visit the farm and see duke my old roster. the other day i went to see him and found him rotting in the middle of the poultry yardhe didn't look attacked so he must have died from a disease i guess. I was wondering if it could have something to do with all the other birds being vaccinated for mareks and him not? a week before he died i noticed that his comb and wattles were turning more purple not the usual blue. i thought i was just him getting older but do you think it could have been a sing of illness. anyone have any ideas on how he could have died and could it infect the rest of the flock?
