Hello, I just joined your site. I'm a chicken addict with an awful poultry habit.
Apologies for the long post. :-/
In response to the Original post (part two) question about trimming ANY feathers:
* Make sure that there are no blood feathers. If birds are moulting, this is likely. On lighter colors, the roots/quills of the feathers will be pink instead of white or whatever. (similar to the visible quick in a toenail). Blood feathers are still growing in, so they have a vigorous blood supply. Cutting these feathers results in bleeding as the feather shaft acts as a siphon hose. The amount of bleeding can be quite drastic and dangerous!
*If you DO cut (or break) a blood feather, you need to quickly remove it by pulling it out with pliers- one quick strong jerk in the direction of growth should do it. That allows the skin to close and the blood to coagulate.
*Leave a little of the shaft when trimming. That way, if you cut a blood feather, you have something left to grasp with the pliers to pluck it.
*Whenever possible, layer the trimmed feathers so that the stiff exposed quills do not contact and irritate any skin. For instance, when trimming flight feathers, trim them just a bit shorter than the overlapping feathers. It takes a little longer to do it right, but it prevents sores and possible pecking from other birds.
*If you trim feathers, always keep styptic powder around to stop bleeding. You can buy styptic powder made for birds, but you can also use flour in a tight.
*Trimmed feathers will not grow back until the next molt. Plucked feathers will begin regrowing immediately. Constantly plucked feathers will eventually lose their color, then cease to grow.
