Yeah Id just stick to what he eats for a while and multiples until he's not a chicken and will eat ONE appropriate sized meal instead of like 3 smaller ones. I have a 1500g female that wouldnt eat anything until I got her these two little ASFs. She's so frustrating. My only picky eaters are my sub adult pastel and my adult female. I hate having to kill and freeze left over rats. It's like I bought these for YOUUUU to kill, not me. EAT DAMN YOU!
