Leaving IXD and following departure instructions; we received a TA/RA. 1 mile or so from our nose was a glider at what looked to be our altitude.  RA said stop climb; so I did.  I turned at a 45 degree [bank] away from the glider and started visually clearing in the direction of my turn when I spotted a second glider just slightly below our altitude and at about 2 o'clock so I leveled my wings. At about that time we received a notice that there were no more conflicts.  We then contacted ATC with the details and resumed following departure instructions.
Learjet 55 First Officer reported airborne conflicts with two gliders during departure from IXD.
