BROWNIE STILL CLUCKING TO HER JUVENILE BROOD

Brownie with her brood of five juveniles and Ralph. Ralph is coming into good feather but is a good 45 days behind the games of similar age and sex. Brownie offspring are nearly as big as she is and well into process of molting from juvenile feather set into the first adult set. The harem stands tight like shown except when feeding although Ralph tends to stand a little apart and out in the open. Loafing sites are much more consistently located in locations that are warmer than average. Ambient temperature was in the middle fifties with a nice breeze. This means they are operating at a temperature that is lower than optimal so they are already doing what they can to conserve energy.




Weights were determined for Brownie (1260 g), stag-1 (1009 g), stag-2 (1236 g), pullet-1 (834 g), stag-3 (912 g), and pullet-2 (974 g). Her non-breeding weight for winter should be about 1450 with empty crop so she is underweight. She is also turning over her body feathers for a second time since summer. Last year I thought same occurred with her and other hens similarly watched. The body feathers kept for the very short time were darker than the feathers coming back in. These new feathers will fade from exposure over the next 8 months making transition to the darker intermediate set more evident. The cocks do not seem to do this. Last year the tail feathers were also turned over twice but that may have been a function of the extreme heat of the summer.

SOMETHING YOU DO NOT SEE EASILY ON EVERY BIRD




Cockerel / stag below represents a colortype where chick, juvenile and adult feather sets are particularly easy to distinguish. Are with key feathers showing juvenile color pattern are the secondaries of the wing.


Juvenile just before first adult feathers start coming in. Note barring on all feathers except hackles and breast.


Juvenile male with many of the juvenile feathers replaced by the first set of adult feathers. Note barred juvenile feathers (secondary's).



Something not shown is the difference in shape between chick and juvenile feathers. Former has pointier tips, especially in tail. Coloration with this color pattern is lighter on chicks as well but not all color patterns follow that trend. When he matures he will look a lot like his great- grandfather Eduardo. Something interesting to note is that such late season stags have almost pullet like sickle feathers while full brothers hatched earlier in season can have pointier juvenile sickle feathers that are a good 2" to 4" longer than the rest on the tail.

Hatch date around August 1, 2013. Current date with bird looking same is November 12, 2013. Age is about 14 weeks for to be in middle of transition from juvenile to first adult feather set on wings. Tail and body are just starting. Transition from chick to juvenile feather set starts around 4 to 5 weeks. Birds will not be in full adult feather until another 8 weeks more pass then there will be an abrupt behavior change in males. Most are what I call adults (bullstags - bullpullets) by around 24 weeks. Some are a bit slower taking about 28 weeks. Nutrition can impact developmental rate as can social situation.

WEANING FINALLY OCCURED 16 WEEKS POST-HATCH

This time I do base it only on lack hearing Brownie cluck. Brownie also pecked her pullets and the stags got into a brief battle royal that Ralph busted up. Despite this, Brownie will likely defend their interest against birds from outside the harem.
 
CLUCKING RESUMED. A WEEK WILL BE ALLOWED TO PASS WITHOUT HEARING HER CLUCK BEFORE SAYING WEANING HAS OCCURED


A couple of hens in cockyard that were not so late did appear to be clucking with offspring of this age but I normally just bust this up so hens can be put through molt under more controlled conditions.
