Hi! I have 10 Bantam chickies (5 silkies and 5 partridge Cochins), and have been keeping their temps by the book (95ish and then 90ish) and by their behavior for their first two weeks. They all seem happy and healthy. So, now, this is their third week, and it is in the 90's outside. It's not quite that hot in the shed where they are, but it is about 81 in there today. I was wondering if that was warm enough without supplemental heat. I read somewhere that Bantams may not need as much heat as other chicks, and that chicks can self-regulate heat after 14 days (these are actually 16 days old now). I'm a little afraid that it's going to get too hot for them eventually!
