I bought 4 adult hens from a feed store the beggining of september. I live in DFW Texas. I bought 2 barred rocks and 2 EE's. After a week one laid an egg, outside in the dirt. Since then no eggs. I found a smashed empty shell in the yard last week. I am thinking blue jays. We have a ton. I just do not understand why they are not laying. They put themselves to bed and i lock them up safe and sound until 7am. They have a large run that they forage in daily. Oyster shell offered and fresh water daily. Help. What else can i do? what am i doing wrong? wanted to add that one of the BRs sings the egg song since the day i got them, the rest are silent.
