I posted other day about temps getting low this week and the use of heat lamp I did securely mount a 100 watt and it helps take the edge off for my pekin drakes. My next concern is its been 20-28 f during day I have a large kiddie pool frozen and a 3 mon old black swed girl who is having a fit to swim they all have heated water buckets in their run to wash face and eyes. After millions of attempts to swim yesterday I cover the big pool with tarp I don't want her swimming in ice no one else seems to care about swimming but her. Would it be ok to fill her a smaller pool with Luke warm water for a bit of swimming or would that do more damage than good. Btw after I put tarp over pool she tried to peck tarp off it was hilarious. I have found my black Swedish girls tolerate cold better than my Pekins, buffs, or crest but they are still young and not as thick as my Pekins.
