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.
When a hen is going to moult, her plumage will take on a very dull appearance. It normally takes about 6 weeks for a young healthy pure breed hen to complete a moult. Older hens will take longer. During a moult, birds do not lose all of their feathers at the same time. This is because in nature, they still need to be able to escape from predators so they do not lose all of their flight feathers at the same time. Some poultry keepers supplement their birds diets with additional protein.
