The Cost of Sinus Surgery. by DC on Aug 23 2012 - 16 Comments. In less than three weeks I will be having a septoplasty and endoscopic sinus surgery. I have essentially had a chronic sinus infection for the past eight-plus months, though Iâve had problems off and on for three years.
Chickens experience two, juvenile or mini molts as I like to call them, before a their first annual molt. The first mini molt begins at 6-8 days old and is complete by approximately 4 weeks when the chick's down is replaced by its first feathers.
A henâs egg production is at its peak from approximately 6 to 18 months of age. Somewhere around one and a half to two years after hatching, the average chicken will go into a molt and lose a lot of feathers and grow new ones. Their protein requirements increase to fuel the feather growth.
