Just a little help, because you're not going anywhere with those guesses:
1)
I A C H N T E S - 1c 1b
M A C H N T E S - 1c 0b
means that the first letter must be an I.
2)
I J K L M N O P - 1b 0c
means that J,K,L,M,N,O,P are not in the solution
3)
I J K L E F G H - 1c 1b -> means only 1 of E,F,G,H is in the solution (a cow)
A B C D E F G H - 3c 0b -> means 2 of A,B,C,D is in the solution (two cows)
B B A A C C E P - 1c 0b -> since at least one of A,B,C must be in -> E,P are out
This post was made before one could know that I must be in the solution. Eliminated since guess 11 (or even earlier): E J K L M N O P
That means the correct letters of guess 15 must be I,D,G which means guesses 16-18 were not giving any additional information.
