I put 3 gallons in the fridge the night before but the thing is, after I cooled my wort down with an ice bath to roughly 95 degrees (the instructions said to get it below 100 degrees) and I added it it in the bucket with the 3 gallons of chilled water, the temp went down to 60 degrees and then I pitched the yeast starter on top of that, put on the airlock and called it a night. I checked the temp this morning when I got up and it's sitting at 68 degrees with no activity yet. Will I have any problems pitching at such a low temp? Also, should I have shaken up the bucket some after pitching? The instructions didn't say to so I didn't. Would you recommend shaking it up now? Thanks!
No, just leave it alone now. It'll be ok, but next time stir it well when you add your water. That way the temperature is uniform and you can check it before you pitch your yeast, as well as take the OG with the stirred wort. Also, stirring it well helps oxygenate your wort for better yeast health. Taking a warm yeast slurry and putting in a 60 degree wort is pretty shocking to the yeast, but it won't kill them. (Don't forget- yeasts are alive and don't like wild sudden changes in temperature any more than you do!) Don't worry about it now, though- yeast is resilient and should do fine. 68 is a good temperature for yeast to work.
