my guineas usually sleep in the tree next to the chicken run- we've never lost one- so about midnite last nite they abandon their tree and sit on the ground by the run chittering in their quiet 'we don't like this' voice, i eventually get them into the locked run for their safety- the odd thing - they usually don't want to be handled- in this case, i was able to pet each one, and gently push them to the run- i was even able to pick one up- very rare- our temps have been cold- about 20 degrees, thurs and fri the night temps will be about 0, any suggestions on their behavior? is it due to cold? should i try to rig up a shelter for them? there isn't room in the coop... i even thought of a heat lamp to encourage them to stay on the porch
