Taimong start molting at 6weeks old..

This is Gutsy's this year's son, DOB is 01.01.2012 which make him 6weeks old now. Took him out from the Ladong this morning and notice his head and wings have many new feathers coming out. Being still new to Shama i do not know if this ever happens before. I check the tail and the tail is still growing because on the calamus area there is still a section of shell like thing which means the growth is still in progress. And also i notice the primary and secondary tail is still the same lenght as the longest white tail. So i wonder how come they start the body molting so early?? hmm...
