I forgot I had another question...my chickies are still in the pen awaiting their coop (they're 3 weeks old). is it a good idea to put a little water in the bathtub and let them splash around a little? (i know, clean out the bathtub thoroughly so no soapy residue is in there). or do chickens not like that so much? I just thought it might be some fun for them since their just hanging out in a pen right now. Thanks guys!
