Oh, I'm so sad this morning. I bought four 3-day old BO's last Saturday. So I'm guessing they are a good week old now. I came home last night and found one that had what appeared to be pasty butt. I thought that was odd as they are quite settled in. But then dismissed it to maybe she fell asleep under the brooder lamp and got too warm. It's been REALLY cold at night so I lower the lamp to keep them at 95. The issue is it's still cold in the morning and so I leave the lamp low, but I also know the garage will warm up during the day. But their brooder is 3' by 3' so they have PLENTY of space to move away from the warmest spot of the lamp. Anyway, one had passed this morning and I'm 99% sure it's her. I know this stuff happens and I probably did nothing wrong. But it's still so very sad. And the sounds that her three sisters are making as they are calling for her. They've been quiet all week but when I pulled her out of the brooder last night, to wash her up, they made this sound calling out to her. It's breaking my heart. I'm not sure I'm cut out for this whole back yard chicken thing. I've had a really rough year with hens turning out to be roosters, bullies, difficult molts, sour crop. Ugh. I can't even list off all of them.
