Can anyone recommend a good size flock of guinea's for 7 acres (of which probably 5 is mowed - last two are thick underbrush) We have 10 chicken chicks now that we're building the coop for with plans to raise the guinea chicks up with some more assorted chicks. We'll then integrate the new chicks with the big girl flock in the coop/run for about 2 months time and then free range the guineas during the day. We have a ton of coyotes, owls and hawks in the area - as well as the usual skunks, raccoons fisher cats, etc. (central massachusetts) Hoping that the guineas will take care of the ticks in field, stay away from the street and come back at night. Any input is welcomed - we're new to chickens and very excited. our current flock is 9 black pullets (unsure of specific breed) and 1 yellowish brownish one the kids named Angel that we're hoping is not a cornish.......
