Hello I'm needing to get some nest boxes.. I had this large metal one that came with our coop. http://www.strombergschickens.com/images/nests/D6S_L.jpg It is rather beat up, has holes.. but I thought it would be ok. It is really too big for my space.. and the large fixed size makes placing it difficult. That and the 3 youngest hens insist on sleeping IN it and making a big mess.. So.. I took it out, added another roosting bar in the hopes that more space to roost would solve the sleeping in the nest problem.. and am wondering what my next step is. I have Aussies, RIRs, BRs and 2 mystery hens.. Would milk crates be a good solution or something else?
