I have four white leghorn hens that I got at the very end of April. I'm not sure how old they were when we got them, maybe two weeks or so? It is nearing August now and we don't have nesting boxes ready. We are in the middle of remodeling and my husband is working on that after work and on weekends so I feel bad rushing him to make nesting boxes. Do you think we will need them ASAP or is it something that can wait until the end of this month? These are my first chickens so I don't know what to expect. Thanks!
