Hello all. I started out with 13 sebrights, now I am down to 6. I don't know why so many are dying and I even asked a vet when I took my snake in and he didn't really have any advice for me. So I am pleading to the experts out there to help me save my remaining chicks. Here is the breakdown: They are currently 3 and a half weeks old. I had many die the first 2 weeks, one had a breathing issue and I searched far and wide into the night hour looking for anyone to help. It ended up dying that night. Then a week and a half of went by and my chicks were as happy as could be. They chirped, ate, flew around, etc. The lady at the store I purchased them from said at 3 weeks to kill the red light, so I did. All the chicks appeared fine with no breathing issues. Next morning one of them had died. They have a red 250 watt bulb, have been indoors in the house at all times with chick starter food and water available and changed frequently, a large cage with room to move around. The coldest it could have gotten in the room was 68 degrees due to the A/C. I will upload pictures shortly. Any help is appreciated.
