Cold Hardy chickens

[Skye727]

I have been reading all about cold hardiness and chickens. It sounds like all of mine will be ok in the winter. I have a barred rock, red sex link, easter egger bantam, ameracauna, rhode island red, silver laced wyandotte, a japanese bantam, silkies and cochins. I was going to give my silkies and cochins a heat lamp, but it sounds like they may not need it. Am I right on this? What breeds are not cold hardy? I'm getting Seramas and I know they aren't. They will be inside.

This link is one of my favorite references, it may be helpful to you in finding out which breeds are not considered cold hardy:

Keep in mind, this is a reference for breeds only, you won't find hybrids on it.
