We have one little chick who needs special care, which is hard because she's our first chick ever! I'm worried she may not be eating enough - she pecks bits of chick crumb off my finger, but it seems such a tiny amount. Is there anything else I can give her? I've heard about supplements but don't know what or where to get them (I'm in the UK). I wondered if it would be okay to grind chick crumb up and dissolve some in water for her (she drinks quite happily) or would that be a bad idea?
