Currently my coop is fourteen feet by fourteen feet. Is that a decent size? I plan to expand it to a twenty four feet by twenty four feet coop in a few weeks once my hen has hatched her chicks and they have grown to a decent size. What is something good to put inside the coop ground-wise? Loose dirt or mulch since grass doesn't grow? I just hate how muddy it is. My coop holds my rooster, Gilman, and my two hens, Edna and Myrtle right now. But Edna is sitting on a clutch of eggs that are supposed to hatch next week. I can't let them free range outside of the coop until the fall, so I just want to make sure they have enough room and won't be overcrowded.
