My blue slate (lilac, lavender?) tom gobbled for the first time today. I had to ask a friend if that's what the sound was! I believe they are about 10 weeks old, I don't remember exactly when I got them. Is that a normal age for gobbling? They, the tom especially, seem to have doubled in size in the past week! ETA: After searching on my computer, I think I've figured out they are between 9 and 10 weeks old. When I got them they were less than a week, but not day-olds. I loaded pics of them on my computer for the first time on April 25th, which was most likely the day after I got them as babies.
