Tari is right, they will acclimate to the house temperature.
But, a heated perch would be fine and your Grey might appreciate the warmth. :-)
Our breeder has huge aviaries outside with Macaws, Grey's, Conures, Ringnecks etc. with no heat. They all do just fine in the Winter at temperature down to freezing.<br><br>Post edited by: danmcq, at: 2007/09/13 14:19
