I haven’t tried any. I had recently developed a problem at my old house but moved and haven’t had one here, at least not of yet. There are multiple neighbors that have cats that roam freely around the neighborhood so I expect that helps keep things in check, at least a little.
It’s sad that C may consider that no eggs = not worth feeding. The logic is so backwards there. This was on my local-ish chicken Facebook group. There’s plenty of stuff that gets posted in the page that’s inaccurate, I frequently share links to articles here on BYC about adequate coop ventilation and describe how to check pelvic bones to assess whether a hen is laying or not. Anyway, this post was different in that it actually seems to have logic and applied science. This was in response to a lot of people complaining about how they hadn’t been getting eggs for 7+ months. I commented to share something that I’ve learned from you
@Shadrach, that the type of shade makes a big difference for a chicken’s ability to handle heat - deep shade vs. areas that are shaded for part of the day.

No Eggs for months? Here's why.
No, feeds have not changed. There is nothing wrong with the feed. It is the protein content, environmental stressors, and natural cycle of a hen's body that have created a perfect storm. For typical laying breed hens, 16% protein feed is standard and sufficient in comfortable temps, 50-80°F. There are variables that can change that 16% protein requirement.
1. Extreme heat. Chickens eat 20-25% less feed in high heat conditions, which means they are not getting as much protein and nutrients as they typically would. Increasing the protein content of their feed to 18-20% in the heat of summer, as well as offering vitamins and electrolytes in their water a few times a week works tremendously. This ensures that even though they are eating less, the feed that they are consuming packs a bigger nutritional punch. Summer 2022 was one of THE hottest on record, so heat stress was a very big factor in egg production dropping. That extreme heat also stimulated the majority of birds to hard molt instead of soft molt as summer began winding down.
2. Molting. Hens do not lay eggs during a molt. There are two types of molts, a soft molt and a hard molt. With soft molts, chickens will only lose 30% or less of their feathers and will complete their soft molt in 2-3 weeks. With hard molts, a chicken will lose the majority of it's feathers, over an extended period of time and it takes 10-12 weeks to complete a hard molt. It also takes 3x as much protein to create and grow new feathers as it does to produce eggs. This brings up feed protein levels again. Feather Fixer feeds are 17% protein on average, barely above most layer feeds (16%) and really don't work well alone during a molt. The nutrients are great, but higher protein is needed to help with feather regrowth.
3. Fall months. Chickens need a consistent 13-14 hours of daylight to produce eggs. With the shorter daylight hours becoming more drastic by early to mid-fall, egg production begins to taper off. Add to it that those shorter daylight hours also stimulate the chickens bodies into starting their molts, and this means egg production most often comes to a grinding halt.
4. Winter months. The vast majority of hens will take a break from laying during the coldest months, it's in their nature. This break reduces the stress and energy expense on their bodies that laying creates and that saves energy is put into staying warm. In nature, food is more scarce during winter, so that energy conservation from not laying would help see them through the winter on less food. Staying warm is hard work, so bump up their nutrition. Some folks don't like their hens taking a winter break, and each keeper makes their own decision about it. That said, to encourage laying in the winter months, switch to higher protein feed (about 20%) and supplement with vitamins, as well as put a bright light inside the coop. The light would need to go in the coop/henhouse and not the run. The light is used to make up for those lost summer daylight hours, so it is typically turned on just before dusk and then turned off again between 9:30 and 10pm.
Doing the math:
High heat: June - August
Hard Molting: August - December
Winter break: December - March

If feed and care parameters were not adjusted, this was the perfect trifecta for little to zero egg production for 7-8 months.
