I am very new to chicken raising. We have finished our hen house and I am wanting to get the chicks out there. My question is, do they still need the heat lamp at this point?? I am planning on locking them in at night, but it is still getting chilly at night here, so do I need to install the heat lamp for them? They have all developed probably 90% of their real feathers, and look like mini chickens at the moment Also, I observed one of my chicks to be laying down a little funny. She seemed to sort of "sit sideways", if that makes any sense. Is it possible she injured herself over night, or could it be growth related?? I realize these two questions should probably be in different topic areas, but it seemed easiest to ask all at once Thanks!
