My Polish Chicks are 6 weeks now and getting a bit big and stinky for the laundry room Now the nights are getting colder and it is frosty I rigged up a divider in the henhouse so they can be seperate from, but still see, the silkies. I put in a heat lamp to take the chill out and was going to check it through the night to see how cold it got, but last night was weird warm outside? How cold is too cold anyway? They are down to about 65 degrees now at the coldest inside. Imput very much appreciated!
