handrearing

I’ve come across my first ever stunted baby and I’ve been successfully breeding cockatiels for 3/4 years. The baby is now 8 weeks old and isn’t far behind her older brother now. She just has shorter feathers than him. BUT I think she might have something wrong with her brain? She’s doesn’t fly...

Hi Guys just wanting a quick question. I am thinking about hand rearing my baby cockatiels because the parents haven't been very successful. I am wondering what age would be okay to take them away from there parents and if the need a heat lamp or something? Thanks Jay :grey tiel:
