That's Annabelle in the foreground. Annabelle is 2 months old now. That comb didn't start until 6 weeks old. I know d'uccle roos normally get big combs early (I'm reading about 3 weeks), but I also know that pullets don't generally get red combs like that at all.
sniff sniff... isn't he lovely? His pal Daisy is a pullet, and thank goodness. She's a crossbeak, and would be very difficult to find a home for had she turned out he.
