I absolutely love the polish breed. I had a buff colored named Phyllis that during the last cold spell I found in the coop had died suddenly. She had been fine. I keep two chicken warming pads. One on the ground for the 2 silkies and I set one up for the polish to roost on. They were using it every night. After Phyllis died it left me with one polish roo. He lived with 2 silkies at night and a small mixed flock during the day. Our recent and hopefully last cold front is here now. Temps in the low teens at night and low 20s during the day. I always offer outdoor run time during the day for all my chickens. I encased the run with plastic so they won't get too much wind. They can always go back into Thier house where it's warmer as an option. The heating Matt is always on. I went out today to find my roo died during the day. Just like Phyllis. No rhyme or reason. It has been unusually windy here the past few days. Should I have left him closed up in the barn with out opening the little door to go out? I have 4 more on order with a delivery date in June but I'm not sure if u should proceed with it. Do other polish owners let them out or keep them in when temps drop below 30? It's one of my favorite breeds and I hate to give up on it if I can change what I am doing. Any thoughts?
