I have 16 hens. Four are 4 years old and twelve are 7 months old. Before last week, we were getting 14-15 eggs a day. We closed off the coop they were laying in last week to move the 3-week olds outside. They have a nesting box that is not as private, but all we have right now. Since then, we are only getting 8-9 eggs a day. Is it due to the change or could it be the heat? It's been mid 80s to mid 90s here lately. Thoughts? Thanks!
