I have 3 RIR and they just turned 8 months today. 2 of my hens have been laying for months whereas my last hen had not until this morning - 1 degrees outside and piper decides to start laying for the first time so to my surprise I had 3 eggs to pick on this crazy cold morning in the Mid West. I do not have a light on them. All I have is a 75 watt red heat lamp (only size I could fit in their coop) My 1st question is: How much longer can i expect my hens to be laying? i thought they would of stopped when the weather turned 18 - 35 degrees. My 2nd question is: my hens do not like the heat lamp (I am assuming) because I have a hard time getting them to go into their coop at night - before the light stayed on (timer goes on below 32 and off at 45) because it has not hit 45 in weeks, i had no problem with them going into the coop. Should i put a bigger lamp? The coop is pretty small for a big heat lamp, that is why i went with the 75 wt bulb. I worry each night if they are warm enough. please help.
