We've raise hybrid chicks a few times and never had any problems. When a fox wiped out our entire flock last year () my kids wanted to get 'mega hens' aka Orpington's, so we bought some eggs online and stuck them in the incubator. We had a pretty low hatch rate and only ended up with five chicks, but after 24 hours we woke up in the morning to find one of them appeared to be folded in half. On closer inspection, she had two broken legs. My daughter made her a 'private nest' in a tissue box and hand fed her water with a syringe, but she never recovered. 48 hours went by and we woke up to another, previously healthy chick, in the same state. The other chicks keep jumping on it and are being really aggressive. We separated her, but she only survived another two hours. Is this a breed issue? Are Orpingtons unusuallly aggressive as chicks? I had read the opposite was true, but I have never had chicks get injuries like this before. They are also the loudest bunch we have ever had and stand very upright squawking the minute you walk in the room. I'm starting to think we have three roosters left. Should we try again? Or should I go back to hybrids...? Do Orpington's need some kind of special care that I was unaware of?
