I used to fill separate hay nets and hang them all over, but I found my little lovebirds would both eat one, then move on to the other. I got a haychix 1” slow feed net and put half a bale in. It takes them a bit over 24 hours to eat it all. I also like the smart pack 1.5” Hay bags, but you can only get 1 big flake in each so they need to be refilled after about 10 hours
