You might believe that it works but scientific studies have proven that no form of capsaicin will work even at an uneconomical amount. Here is the math. 25 kg of layer pellets is 25.8375 quarts, one quart is 64 tablespoons. That is 1635.6 table spoons. In the scientific study below they used 4% of capsaicin which would be 1kg or 2.2 pounds. I found 250grams on Amazon, $17.00 plus tax and shipping, $64.00 plus tax for 1 kilo plus tax and shipping.
BTW, with kilograms the math is far simpler. 4% of 25 kilos is one kilo.
Tractor supply as 50 pounds of layer pellets for $16.99 so right away you see that a bag of treated feed to the levels used in the scientific study costs around $70.00 on top of the cost of the feed, call it $90.00 per bag by the time you pay the sales tax on the feed and the capsaicin to treat it to the bare minimum as in the study.
5 times the feed cost with no benefit and that much capsaicin cannot be healthy for the hens. Your two tablespoons just make you feel better.
Now, I am a lazy person at times and I've posted this same info to dispel the same well meaning misinformation several times so forgive the copy and past from a past post about capsaicin. The math on the capsaicin might be different due to recent prices.

"This would be awesome were it actually a valid method but too many studies have been done, peer reviewed studies, to give much credence to capsaicin working long term. Here is an exert from one study. To set it up, they offered two feeds,one treated with capsaicin at different heat levels (SHU) and one normal feed. Plus they had another study done previously as a control, just plain untreated feed.

For both treated diets, results of pairwise comparisons reflected perceived differences in alternative feed that was available to rodents among sites (Table1). At sites 1 and 3, additional feed
sources, were low to moderate, and feeding stations were located in small buildings(45 and 20m2, respectively). Similar patterns in response to the treated diets were observed at each of these sites.
Initially,consumption of the poultry feed decreased dramatically at sites 1 and3 when the 2000SHU diet was offered, and remained low for 8 days.Thereafter, feed consumption increased and approached pre-treatment levels of consumption. Tolerance of rodents to the capsaicin may have increased over this time period and, with a lack of alternative feed, animals had probably reached some hunger threshold.
At site1, rats did not decrease feed consumption when offered the 3000SHUdiet. Previous exposure to the 2000SHU diet may have increased tolerance to capsaicin. In additional, rats may have become more dependent on the poultry feed. This explanation is supported in part by the increase in consumption of the control diet over thethree2-week periods that it was offered at site1.
Consumption of the control diet did not change over the study period at site 3,
but consumption of both treated diets increased over the 2-weekperiods they were offered. Moreover, carry-over effects may have influenced feed consumption when diet treatments were changed,although visual inspection of the data suggests that any such effects were likely minimal (Figs1and2)

In short,they found that adding capsaicin to chicken feed did produce
temporary results until the rodents became accustomed to it,then the liked it as much as the untreated feed. But, in the short term, it did lead the rodents to prefer the bait they set out, albeit bait without the poison. Obviously they couldn't use poison b it or their rats would die so they used the bait without the poison.
The bad news, 4% by weight capsaicin was used. An ounce of pure capsaicin runs $20.00 on
Amazon.A bag of feed, 50 pounds, needs roughly two pounds of capsaicin. Do the math, even a one pound container of plain cayenne pepper costs$20 plus shipping so $40.00 plus to treat one bag of chicken feed. It would be cheaper to just buy more feed for the rats.
What you saw was real but it was the initial reaction to something unfamiliar and rats are very smart. When he got hungry he would be back and in a few days it would be eating as much as before"

Back to the study, using the capsaicin does work for a few days and it can be used to drive rats to eat other feed laced with poison, maybe. But on its own the rats get used to it, then they prefer it. Look at the last sentenced emphasized in bold text.
