My three barred rocks started laying in April. The eggs were the classic brown color, basically the same color as store-bought brown eggs. Around June and July we got about one egg a day from each hen -- each afternoon there would be three in the nesting box. Then a few weeks ago, they started laying infrequently. Now we get one new egg every two or three days, a drastic decrease in production. Even more strange, the eggs are now cream-colored instead of brown, and slightly larger than before. Anyone familiar with this situation? No changes in diet whatsoever. Did the heat finally get to them?
