"To the people who have egged the new logo... you are a disgrace to this world," he wrote.

"How disrespectful can you be."

Fans have been quick to come for the alleged 'eggers', questioning the motive behind the attack.

But others came to throw stones.

The egg attack comes after key defender Dougal Howard was traded to St Kilda in a decision rubbished by former premiership winner Kane Cornes.

Howard and veteran ruckman Paddy Ryder made their way to Moorabbin on Tuesday, traded for St Kilda’s picks 12 and 18, along with a swap of future third and fourth round selections.

'Stitched up'

Speaking on AFL Trade Radio, Cornes didn’t hold back when dissecting the Howard trade.

“Port Adelaide have let a player in his absolute prime go,” Cornes said.

“Port Adelaide have completely botched this in my opinion.

“In this deal, the Saints have absolutely cleaned up. Watch Dougal Howard absolutely bite Port Adelaide here.”

Describing Howard as a potential future All Australian, Cornes said it was frustrating the club wasn’t listening to its members.

“It’s time Port Adelaide listen (to the fans),” Cornes said.

“They didn’t want this deal to happen.”

The egging incident appeared to prove Cornes' point.

Howard’s manager David Trotter confirmed Port’s decision to play the 23-year-old as a forward, rather than his preferred defender, played a role in the club move.

“When Jason Cripps and I sat down and did the four-year deal Doogs was playing as a key defender,” he said.

“There was a change in coaches, change in mentality. “I think St Kilda have brought him in to play that key defender role.

“Doogs went through that (decision to leave) process at the end of the year but really saw the opportunity to go to a club with a young list to play as a key defender.”

Describing Howard as a “pretty loyal kid”, Trotter said it was a tough decision to make to leave the club.

“In the end Doogs has made a decision hopefully for the betterment of his career to play as a defender at St Kilda for the next eight to 10 years,” he said.

“Port were really clear in that they saw his future as a forward.”
