Feeder forum! - Question about Pinhead Crickets

Hi, do pinhead crickets get to be full grown after awhile like a large cricket? Just wondering. Because I ordered 5k of them on accident on the internet. And just recieved a tube of them... And how long will it take to be a smaller then medium look. About 00 1 or two of those 0's? most likely 2.
Oh and I definitely think we hshould have a feeder forum. But most likely no one will listen to my ideas.

 

yeah pinheads are baby crickets if kept in well conditions they will become adult large crix

 

i think i have heard it takes 4 weeks to become adults but im not 100% sure, im better with the worms.

 

took my pinnys 6 weeks for mine to get ready to breed again. depends on how you feed them.
