Be prepared for those quick babies to jump out as soon as that door opens. I used to put down a very large thick comforter to cushion the floor if we were holding chicks in case the little buggers jumped unexpectedly. Barriers mean nothing to them ~ chicks can jump high & far for not having any wing feathers yet! Your aquarium w/ the ventilated screen looks nice plus see-thru!It's a front-opening tank actually! That's why I thought it would work out better than a big rubbermaid tote
