I have 2 pekins... just over 3 weeks old .. my question is - they seem to have a little bit of crust around both eyes...( not so much that they cant open them.. just enough that it looks kind of wet i guess..if that makes sense ) they have a large bowl of water that they can dip there heads into, but I rarely ever see them dip there whole head in... They eat like crazy, and are otherwise perfectly fine and active... is this normal??.. a stage they go through??..
