After working so hard, trying to incubate I had 4 healthy chicks at the end of the day. I have 4 with navels that aren't closed up. The four healthy chicks were crawling and pecking at the sick ones, so I decided to put them over to the brooder. Only all my brooders are full, so I made a makeshift one. I didn't think it was too hot it was only a 75 watt bulb on a cardboard box, but 20 minutes later now, they are all dead. I can't believe I made such a stupid mistake. These guys were so healthy and vibrant, and I roasted them. One was a Barred Buff Cochin that I have been hoping so much for. Another was a Black Rosecomb. Another I don't even know what color the initials stood for br bbr Rosecomb. And the last was a mixed breed. I have 2 sick rosecombs as of right now, and 4 sick Columbian Rocks. I am ready to just give up.
