Well, the first one and the third look like cockerels to me. The ones with the saddle could be pullets because the are going bald in the back because the cockerels are attempting to mate them. Just a thought. The second one looks like a pullet to me, but I could be wrong. Hope this helps!!!!
Can I add on leopard geckos that they can not eat KING meal worms. They can have some like twice a year maybe, but can cause them to become over weight. Mine is already fat on crickets at least his tail.
