My 14 chickens which turned 1 year old last March, started in the last few months making like 2-4 eggs a day. Neighbor said they were likely changing feathers. Now she came to see them (I am giving them to her) and touched them near where the eggs come out and said that out all 14 only 5 were good layers and the rest were done for life. She said the barred rocks are bad layers in general and out of my Jersey giants only 3 were ok. Is it true you can determine how good a layer is by touching them near their rear, and how can they be 'done" already if they are only 1 year and a half? I am afraid she may be planning to butcher them I want more chickens in the future but want them to lay eggs for at least 5 years, is there not such a thing?
