pinkys wont move around enough to stimulate feeding responses. try hoppers for the normal size guys and maybe a small hopper or fuzzy for the bitty there. He has a nice looking belly (full of yoke) so he doesn't look to be in danger right now. Give him a try every 4/5 days with a live fuzzy and if he doesn't take by the third attempt i would probably assist feed him (I wouldn't let someone that small go toooo long without a meal.)
Good luck with him and his clutch mates, get some updated pics after they shed![]()
