This is our first year raising chicks (four - almost 3 weeks old) and the first time building a hen house. We got a small henhouse from Jax, thinking it will be ok since the hens will have a big run and we'll let them out in the yard for even more fun. But from reading reviews of the henhouse online, it appears that raccoons can quite easily pry off the floor of the elevated nest box and then kill the hens. I have finished putting the henhouse together with the exception of the nest box. Any ideas on how I can make it safer? I also plan to have a plywood floor connected to the house so critters can't dig under.
