Hi, I have serama's and now have them in the house so that they will be safe for winter. I could heat the coop outside with a light bulb, but am concerned that on cold days they would still be in danger, as they don't stay in the coop during the day. So I have them indoors in pens, in my heated finished basement. I have raised conures for years and they are inside. I just give them calcium d3 for their health. I will be giving the Serama's the same. My question is will it make them sick, if on warmer days, I take them out doors? There will still be a temperature change from inside to outside. I hear that they can handle down to 40 degrees, so maybe on days that are 50 or above, I would like them to get some sunshine for their health, but coming from a 70 degree house will be a bit of a change. How do you all handle your serama's in the winter? I am using shavings in the house and concerned about dust coming through the furnace. Wood pellets are way too expensive to use. Is there a better solution? Sand would be dusty also. I love my babies though. So sweet.
