Chickens or Monkeys?

 I went to a charity poultry auction a week ago on sunday and came home with 4 white silkies and 4 araucana's, around 17 wks old. Well they were out in there run all afternoon having a good scratch around but when i went down to put them to bed i couldn't find 2 of the araucana's ? i serched everywhere. went to let them out in the morning and there they were in the run having breckie. Same happened the next night, but in the morning i went down and there they were right up in an old oak tree, at least 20 ft up, i called them down and they both flew straight into the run for breakie!! fence around run is 10 ft high. So spent yesterday putting netting over the whole area to keep the little monkeys in. 10 mtres by 4 metres = £50 quid in netting and i thought they were a bargain?? 

I do keep trying to warn everybody that Araucanas are more closely linked to jungle fowl - hence why about 6 of mine roost in the trees along with my guinea fowl 

They are cheeky little things, i looked everywhere except upwards...silly me
