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.
Molting is the natural shedding of old feathers and growth of new ones. Chickens molt in a predictable order beginning at the head and neck, proceeding down the back, breast, wings and tail. While molting occurs at fairly regular intervals for each chicken, it can occur at any time due to lack of water, food or sudden change in normal lighting conditions.
