The lead didn't last long however and within 10 minutes of leading Blues found themselves behind in the game - Villa defender Ridgewell bringing the scores level and then Cooke giving them a lead.
Blues only other notable chance in the first period was a 25-yard shot from Jovan Kirovski that went wide of Postma's post and Villa went into the interval with a single goal advantage.
The second half lacked any real goalscoring chances although Stern John did head over with a half chance from a corner kick and Coly unleashed a powerful effort from 30-yards out on 75 minutes.
Paul Devlin was booed for most of the second half by the Villa fans for two very late challenges - the second of which earned the Blues winger a yellow card.
So Blues were unable to record back-to-back wins in the Premiership reserve league but they have a quick chance to get back to winning ways with another game on Thursday night against Sunderland at St. Andrew's.
