Our 5 person family is raising 6 hens for eggs and pets next month. We are ALL really excited. We have picked our breeds already. We have our heat lamp, feeder, water, and know what our brooder box is. We plan on keeping our hens inside until week 6. We will get them at day olds. Our brooder box is a rubbermaid box. It is 4 feet long and 2 feet tall and 2 feet wide. Is this big enough until they are 6 weeks? Thanks in advance!
