Can chicks under 3 months eat pecan tree pollen thingslings ?

[ladyearth]

First of all when I preview most times my subject like post title disappears... whats up ?
Their kennel is under a pecan tree. Lots of those dangling pollen things everywhere. I see them peck at them.. But they try almost everything.... So is it okay and its it any nutrition.???
so are the big chickens run but I dont know if they even peck at the dangling pollen
Thanks all

Both my coops are under pecan trees. I think there is no problem with the pecan stuff. I am of the belief that chickens will not eat something that is poison or very bad for them.
