Well I have read numerous threads on here trying to learn as much as I can about my chickies and how I can b the best chickie momma I can b. They r due to go out in the new coop and new covered run this weekend. They just turned 6, 7, & 8 weeks old today. So I have been slowly weening them off of the light at night. I have a red 250 watt heat bulb and a regular work light bulb. I use the white light to simulate day and night and the red light at night. They aren't benefitting from the heat because they r feathered out and don't need the heat. It is about 70 degrees at night. Last night was their first night without light in the brooder. I checked on them numerous times for the first 3 hrs after I turned out the light. I only heard a few contented cheeps. So I figured everyone was fine. NO one was cold and they were ok with the lights not being on. When I got up this morning and went down, one of my polish roo's (6 weeks old) was laying on its side, stretched out. I thought I was going to see a dust bath or he was just stretching out. So I poked him not believing that anything was wrong and he wouldn't move. I picked him up and he looked me square in the eye and was very alert. I took him out side and tried to get him to stand up on the truck tailgate and he would just fall over and his legs would twitch. I started bawling and hollering for DD who was getting ready for work. I told him I thought that they got scared last night and piled up and he was at the bottom of the pile and had broke his back or something. I held him and felt his legs and back and worked with him trying to get him to stand, but he just fell over and his legs would just twitch and his toes were all curled up. We were at such a lost as to what to do. I have never killed an animal in my life ad DD wasn't keen on it either. But with the twitching and curled toes we thought it best to save him from pain. DD took care of that and we buried him. I am so devastated. I blame myself because if I would have checked on them better (I'm saying better because I didn't actually go down to see how they were laying - I figured they would cheep if the were cold or scared within the 1st couple hours and they never did. So the moral of my story is that until my chicks tell me they r ok to sleep in the dark, they will have a small obsure light on forever!
