I am currently a happy serama mamma of 8 four month old seramas. I am new to this breed. I admit that I foolishly didn't research as thoroughly as I usually do before making any animal purchase. I assumed that seramas would be exactly the same as regular chickens which I've had for the past 6 years. Since they hatched, I have been reading about them more and I discovered that seramas do not do well in the cold weather. Unlucky for me, I live up north east of USA. While the temperatures don't usually stay in negative digits, at night at some times of the year it is possible. I was wondering if anyone here has any experience with this and if so, can they help guide me for what I'd need to protect my tiny chickens? I am wondering it is true that they can die in temperatures under 40 degrees F? Is there some sort of small safe heater I can purchase that will keep them from freezing? Do I have to bring them inside the house for the winter, and if so, how much space will it take? Also, two of them are roosters- how do you keep them from not waking you up at 4 am when they crow in the house?! I keep mine in an 8 by 8 by 8 foot 'room' of my coop with insulated walls- however not all of the coop is insulated- I am almost certain that the windows are possibly drafty. I'd like to keep them outside all seasons if that is possible. Are there such things as barn heaters or coop heaters? I really do not want to use heat lamps or anything where a fire could happen. Are those chicken warming mats suitable? Would that keep them warm enough in the minus digits? Are they a fire hazard at all? By the way they share the coop with regular sized chickens, but are in a separate 'room' in the coop, so if I put heat in there, the rest of my standard sized flock will get some heat too... is this bad? As you just read, I'm loaded with questions and concern of their care... I'm just hoping someone has some experiences with this they can share. Many thanks in advance for any replies.
