My birds are too hot and the chicks in the shed are even hot without the lamp, the door is open too. Don't know what else to do for them they have shade, ice water and lots of cold veggies out of the fridge but they are still panting in the shade. We are so not used to this type of weather over here!! I've got burnt and my arms are killing me just feels like there is no air.
