I don't really think any color is rare, Silkies are a very popular breed, but if I had to pick a color that I had the hardest time finding it would be black. I breed blue, black and splash Silkies (currently, I've had lots of colors and hopefully at some point will again) and had a very difficult time finding my black rooster. Most folks selling blacks are usually (and unknowingly) selling really dark blues and the only way to find out the difference is to breed them (its pretty disappointing to find blue chicks where they're supposed to be black).
I don't envy your weather one bit, sorry! We've been in the 70s and 80s the last few days and I'm not looking forward to the cool front coming in....which will put us in the 60s
And they'll be fine on the medicated feed. Personally, I would take it back to the store and exchange it, but I don't use medicated at all. But, if you don't feel the need to return it, go ahead and feed it and then switch them when the bag is gone
