Husband ADHD

My husband has ADHD & is bipolar. He is on medication to treat both. He still goes through this periods of finding something that interests him & fully engulfs himself in it for like 2 weeks, gets bored & gives it up.

This time he’s obsessed with chickens & it’s starting to drive me absolutely nuts. All he talks about is chickens, what he wants to get for the chickens, what he wants to build for the chickens (even though he doesn’t have any carpentry experience), etc. Every time he talks it’s about chickens.

I feel bad for getting irritated because I know he can’t really help it… is there anything I can do to help him get through this phase faster???

Edit to add: I know it’s not hurting anything other than my sanity. But you sit here for a week & listen to someone talk about chickens literally 12 hours a day & see how you feel at the end of the week. 🥲
