I am looking to breed smaller comb legbar roosters, As I recall the comb is only 4 points when they are judged.
However, if that does not happen and I do not get rid of the legbars,
I am looking at some of these from Amazon

That's a handy little device! It can warm up to a toasty 45 during some days and plummet to negatives at night, so that might be worth checking out! Thanks Ralphie!
