It was the Ducks at home to the Linnets, but a 58th minute howler from Dean West made the visitors look like turkeys.
West no doubt was trying to find the centre backs with a square ball on 58 minutes but instead found Danny Mead, who fed Drew Roberts to slam in and give John Higgs no chance.
Boss Tommy Taylor tried a new 4-1-3-2 formation with Mark Camm in front of the back four, Matt O'Halloran in midfield and Robbie Harris making their first starts of the season.
It resulted in the best performance so far in this campaign, but missed chances cost Lynn dear as they lost to a single goal for the second time in four days.
Harris in the first few minutes laid the ball through to Danny Bloomfield, who rounded keeper Jack Rashid but delayed his shot until McCafferty cleared it off the line.
After that opening 20 minutes, Aylesbury sub Paul Edgeworth cleared the bar, while Roberts picked out ex-Linnet Darran Hay, who headed into Higgs' arms.
That was it from Aylesbury for the first half.
Jack Defty, back in midfield, turned provider for West, who was down the flanks with Adam Smith, but his left-foot fizzer was agonisingly the wrong side of the post.
After the break, Defty headed into Rashid's arms following an O'Halloran centre.
In the 63rd minute, Simon Clark missed the target with a header. Then Harris laid back to Cooper just on the edge of the box, but he shot over the bar.
On 80 minutes Matt Hayward headed wide for Aylesbury. In the closing stages The Walks outfit pushed forward, and sub Sam McMahon set up Bloomfield, who again wasted a good chance.
