I bought silk worms from Mulberry Farms and I decided to get crickets from them since I was already ordering. I got the smal which is from 3/8 to 1/2 inch in size. When I got them and took a look at them I am not sure if they are ok to feed to my chams or not. One was born in October and the other 2 were born in November. Is 3/8 and 1/2 crickets ok for their age?
