I would have to say the same as the others .. Contact Animal Control call daily if you have too.. Tell them about him not feeding them.. Offer to help your friend find homes for the extra roos... Also I would print out info sheets and constantly push him/her on the facts of raising birds... Just that they arent getting eggs is a red flag... Others say I'm mean because I will push and push when I see animals not being cared for properly,, I don't care that its their home... The animals can't control how they are taken care of... If all else fails though you may just have to decide whether you want to continue to be friends with this person and just step away... Hopefully they will realize that you care for them and they will try to do better....
Sorry didnt mean for it to get that long
