That makes me feel significantly better lol. When do females combs start to turn pink? My chick's comb is starting to look pink but is definitely not really red like the 6week old cockrel you posted.
Again, it varies, but in general, Delawares are fairly early maturing. I'd look up photos, but I haven't had any really young pure Delawares for a few years and it's hard to find them all. I can't remember where I put those on my computer and various photobucket files, imagine that, LOL. I've raised Delawares for about 6 years or so. Isaac, my 5 year old rooster, wasn't my first breeding male. I had to cull my first pick from a different line when he became aggressive at about 24 weeks old, only rooster I ever actually processed and ate. Before that, I had some chicks hatched from a hatchery pair my friend owned and hated them. They were gone from here by the time they were about 8 weeks old if I remember right.
