I hope you manage to get bun eating hay, I have been fighting the same battle to no avail.
I have tried EVERYTHING. Every hay under the sun (the bags I have thrown away is ridiculous). Putting it in a litter tray, in a hay rack, in a box, in toilet tubes, putting forage in it, hiding veg in it, cutting down pellets and veg (she just lost weight).........my list is endless.
Poppy would literally starve than eat hay, she is a dental bun so I can only imagine it is painful for her to chew. The only time she will put hay in her mouth is when she is waiting for her breakfast or tea and is 'starving', she will literally be chewing one strand with is sticking out her mouth (it never actually gets eaten, just chewed on for effect) and will be looking at me as if to say 'look what I have had to resort to because YOU won't feed me). :lol:
It's a nightmare because I never know if she is hungry or just greedy, with the other buns I can always assume that if they are hungry enough they can eat hay but she can't, I have to go by her weight. As a result of all the pellets I have to feed (soaked so she can chew them), her partner is getting tubby to say the very least.
If you come up with something that works for you please do let me know. :wave:
