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.
Some chickens will go into moult early but the process lasts over a longer period of time simply because they do so at a slower rate. Early moulters can shed their feathers for up to 6 months before fully finishing but as they lose a feather a new one grows pretty quickly.
