Year before last they were in my chicken coop too much mess, this year they were in a 10x10 tractor, not enough room. Next season I would was thinking about fencing off a pad of about 20x30 for 50-100 birds.. I am looking for input from anyone who has tried this. Is this enough room as far as the amount of poo they produce? They will have a hoop house to get out of the elements that can be moved but the pen itself will be stationary. Thanks in advance
