As we know, I live in Central FL. It got super cold here last night so I threw down a large handful of coastal (fine) hay for Momma & her 4 week old chicks to nest in. When I came back two hours later EVERY LAST PIECE OF HAY WAS GONE!! They ate it!!!! Am I to expect blocked crops now? And, how would I know if it is a blocked crop? Naughty chickens!
