The moulting hen has scaly leg now too!

Hi, so I'm more relaxed about my hens moulting, but the vet diagnosed scaly leg and says I need to soak her legs in surgical spirit once a week for I can't remember how many weeks.
I have to look at the other's legs to see if their legs are bad too, and treat them too of course.

I need to review the coop and aviary, but in the meantime could anyone advise me on how to disinfect it please?

Oh, and yes I need to worm them too.
do they have the live yogurt after the course of wormer?

Many thanks

Thanks Sassy, yes he's a real chicken man and gave me a lot of useful advice on how to improve the aviary.

May I ask how to give the wormer Flubenvet?
it says to mix 6g with 2kg of feed but I feed them layers pellets.
is it best to change over to mash in order to worm them, or is there something else?

I'm learning a lot this week!
Thanks
