i want to build a coop that has a small floro light in it on a timer so they can have the same amount of light all year round. also here in tx we do get snow so i wanted to hook a water heater thermostat to another light fixture and but a red heat lamp bulb in it to keep the coop warm during cold weather. my question is can chickens see red light. i dont want them to see it but just get the warmth from it.because if they see the light i have a feeling that it will keep them up and really cause health problems. i have looked through all my chicken books about this but nothing. Thanks Rod
