I tried heating their regular feed up. Once. I vastly prefer heating plain water then stirring it into their feed. I try for nicely warm food; not cooked even if it is cooled afterwards enough for them to eat it...
Or should I just use their layer food snd mix it with water and heat it up
Any suggestions would be very welcome
Also heard conflicting ideas about protecting combs and wattles from frost bite
I know about the humidity factor in this but ..
Protecting combs and wattles from frost bite: yes, humidity is the biggest thing. Also, not letting them run out of drinkable water (dehydrated birds have less blood flow through the combs and wattles). I think rubbing oils or lotions onto their skin does not help and often harms. I can't find peer reviewed studies on it either way, though.
