Those guines have been housed with the peas they will be fine.How old are these peafowl? Did you raise them or did you buy them? Are you willing to take the risk of them not coming back? I know someone who went to free range their peas and she had guinea hens. When she let the peas out the guineas went after them and attacked then so the peas flew away. Unfortunately they never returned. I know I gave her the pair of IB split to charcoal peas. Easy to let them out when they don't cost money but when I told her she can get another pair for $300 she no longer speaks to me LMAO! So this is something to think about.
