Swindon had taken the lead before being reduced to ten men and the Scotsman believes that the red card had a big impact on the eventual outcome.
“We went 1-0 up and had a few more chances but I think the sending off changes the game,” he said. “They came at us a bit more and the boys started to tire but even though we were down to ten they weren’t creating too many chances.
“We still had a few on the counter attack that I think we should have taken and we’re looking at it as two points dropped to be honest.“
Despite creating chances, Ferry says that there is no excuse for not winning a match at home against opponents in the relegation zone.
He continued: “The boys dug in really hard but it’s never easy with ten men. We kept going, got men behind the ball and played on the counter attack and I think that worked.
“We had two or three chances that went just past the post and one that Gary Roberts put over the bar so I think the boys were a bit unlucky but we should be winning games like this.”
