So sorry to hear that!!!I was soooo up after getting eggs in the mail then I went to the barn.... Bulb blew on my 4 week old Australorps and I lost 17I just replaced the bulb 2 weeks ago. I had just let my "old" girls go and was counting on this batch to "update" my flock. Now the girls I kept are not laying. I don't know what I'll do. It's crazy to get so attached to baby chicks. So many things can go wrong....
