maybe if you put the guineas seperate during breeding season? I'm trying to work out possible solutions if a problem arises with our six guineas. I simply do not have room for 10-15 of anything that is a permenant resident (the meaties in their tractor don't count!). I'm thinking that if it's just a breeding season issue maybe we could put the breeding birds in the turkey tractor (4x12x6 feet high) during the mating season then let them back out? I guess that depends on how long the mating season is too... Better put on my researching cap!
