Sorry, I know this question is asked a lot, but everything I've read recomends leaving the hen with her babies until she rejects them herself. I would love to do that, but she's a real meanie and when she does decide she's done with them I'm pretty sure she'll kill them if I don't separate them. The chicks will be just over 4 weeks old when I leave, and almost 6 weeks old when I get back. My neighbours will be keeping an eye on them, but they work full time so they can only check in on them in the evenings. What are the chances that she'll reject the chicks before 6 weeks? Would it be safer to separate them before I leave? The weather here is fairly warm at the moment, so if I do separate them I'd like to do it at around 3 weeks to give them all a chance to adjust under supervision and be sure they're ok before I leave. Any advice greatly appreciated.
