treating frightened chickens.

I have been enjoying reading the forum and noting advice as I have only had my two birds for three weeks.
 I am concerned though, as how I can check for parasites or do anything with them where they need handling.  They are becoming a little less  shy, coming for food etc. but keep their distance always.
Clipping their wings was a major task needing a quick grab in the coop and a cloth thrown over their heads. 

What will I do if they need powder for getting rid of mites?

They will become better dont worry! In the meantime if you do need to handle them do it at night after they have gone to bed as they are so much calmer when they are sleepy

Thanks for replying.
Yes, they are laying, but when approached, rather than crouching down, they turn and walk the other way!
We use a handful of corn to entice them back into the run but will try to get them to eat out of our hands.

It sounds hopeful that it will become better, especially as we are spending a lot of time with them.
 Nobody told us that housework doesn't get done when you have chickens. We choose jobs in the garden where we can watch them!

If you kneel down and put the bird facing you between your legs it will calm down (and can't move anyway) so you can give it a good dusting. They have a sense of humour and will play games with you. We have a rule; if I pick up a sweeping brush then no games, I mean business. Otherwise they do as they like. Try doing something like checking the tyre pressures on your car. You'll have lots of chook advice, one running off with the dustcaps, one on the pump and the others so curious that you won't be able to see the valve. Have fun
