I built my nest box out of white 2x4'2 and osb. Its 14x14. My 2 RIR ( 20 weeks) started to lay in the poop catcher under the roost! So I took it out. Now shes stuffed in the box and just looks miserable. I Can build another one today, only took me about 30 mins to build ( first thing i built too!! ). I was thinking double the size. Any suggestions or good sizes. Theres a liner in the bottom and pine shavings and then hay. Thanks!
