ok, i have GSL hens some about 2 years old and some about a year. last fall they were all laying great! 15- 18 eggs a day... the days started getting shorter.... so i added a heat lamp. but they still slowly tapered off on laying! so i have tried the red bulb in the heat lamp and the normal bulb. i had it on a timer also.. they get freechoice layer feed and have a huge container with oyster shells... their nests are clean... every one seems healthy.. i dont get it?? i also have bantys that are a year old to 8 months old and they have never laid!! ACCKKKK!! they arent hiding them i know that!! ive wormed them and everything. the roo even stopped his romantic attempts! wil they pick back up as it gets warmer?? the last egg i got was in december , a tiny tiny egg dark brown. before that, it was the first week of november!! help!
