I have 6 guineas, 2 male, 4 female. They are 17 weeks so they are relatively mature and are most likely physically able to lay eggs but its fall so they are not. What is the best strategy for getting them to lay eggs during the winter? And another quick question, how do I stop my guineas from attacking the chickens, I always thought it was a territorial thing or something of that nature but they seem to do it for fun, every chance they get they will attack. (they were raised together but now live in separate coops).
