Hi all, this isn't a color mutation question but a size related question. I just recently went to a bird show with a good number of IRNs and was fortunate enough to see pretty much every mutation readily on the market (very tempted to grab a violet!)

But as I looked at all these birds, I noticed that they all seemed a bit small compared to my Sukha. The younger birds that are the same age as him were slightly over half his size and even as I held adults they seemed so small in comparison, maybe 70-80% of Sukha's size but they were all about the same size as each other (including his own parents who were at the show!), so it made me wonder why Sukha is huskier than other Ringnecks at such a young age (taller and thicker)?
Is this just a chance growth/size deformation or is there something I should be worried about? I haven't gotten a T-stand to weigh him yet on my kitchen scale, else I would furnish that information.
Thanks!
