I was told when I bought my chickens that 2 of them are broody hens and very good mothers. So, my question is..is there a certain time that they should go broody? I know what to look for and they aren't showing the signs. Also, my hens, during winter layed up to 15 eggs per day, now that the "warmer" weather has come they seem to be laying about 9 a day...what is up with that? I have noticed that a few of them(maybe 4 or 5 ) are molting...does this affect egg laying?
