We hatched these 2 blues this past summer and have now been offered 2 hens from a friend to go with them. I do not know how old the hens are but I do know they are older than 3 years and have reproduced in the past. Can anyone tell me how they will do with our boys? Will they be able to breed this season with our boys? Or will ours even be interested? Also, can a person use Ivermectin on peafowl, and if so can you put it directly on the skin like you can with a chicken? And if so how much? We use 3 to 5 drops under the wing on our chickens of Ivermectin, injection type, with good results. Oh, and one more--is it all right to feed black sunflower seeds to our peafowl? Are they too high in protein? We feed our guineas "BOSS". Can the peafowl have this or is that a good idea? Right now their main diet is lay pellets.
