Building a new colony. Part inside and part outside. The inside is approx 10' X 14' and the outside is 10' X 18' with seperate buck space off the side the whole thing has a dig barrier approx 2 1/2 to 3 feet deep all around it. The does can go from inside to outsice at will the bucks have an inside and outside also. Wanting to house my 6 does in the area is it large enough? Also I've heard in colonies there can be a flea problem. Never had fleas in by cages don't know about colony life. Any advice would be very welcome. My rabbits are all meat muts Lope, New Zealand and Flem.
