I thought they went from your place to your BF's place? My mistake then.
Well, it could be anything others have said. Egg eating, heat, stress, protein or just plain not old enough yet. If it was one bird, I would wonder if it was an internal layer, but that's not likely with several birds. I'd ask the breeder you bought them from what was the average age his hens started laying. Mine generally start laying at seven to eight months.
they came here from my bfs place. I do not believe its internal laying, as they are acting just fine. Heat, maybe but if thats the case I will never get eggs from them, but they are given ice water, watermellon ect to help keep cool. It couldnt be protien or lack of neutriance as all my birds here are producing like champs. And they are very mature age and lay eggs.. just not wanting to.
