So here in NJ we are in the midst of a pretty tough cold snap (10-15 degree nights are expected until Sunday), so I went out and bought a heat lamp, because I have one bird in my flock going through a molt. So, after installing the lamp in the coop with some duct tape and a clamp, I tossed the thing on this afternoon as a test run and got some unexpected results......Birds fighting and pecking at each other, intense stare downs, jumping and clawing with their talons, noises that I haven't heard before and some shrieks that did not sound pleasant. This all happened within roughly a 5 minute span, so I unplugged the thing, and life was back to normal. They walked around, ate together, drank, and just acted like normal chickens. My question - what the hell was that about?? I have never seen any behavior like that from my birds, and I don't want to ever see it again. I made sure that I got a red heat lamp so that they did not extend their laying cycle or think the day was extended. I was merely trying to give them some extra warmth while we experience a major cold snap. What was wrong here?? The light is red, out of their reach, 250W bulb...Can anybody offer any advice as to why this happened, and what I should do?? Should I take the light back? Thanks!
