Interesting thoughts Lady Mc. It entirely makes sense to me. I wonder if Centrarchid cares to respond. He's working on a line of self sustaining Dominiques, so might have some input re: broodiness related to molting.
My girls were hatched in Feb and early March. They've all gone through at least a bit of a molt, with the RIR going through a hard molt, just now getting back some feathers, BSL going into a fairly heavy molt. EE have done a light molt, mostly beards, anterior neck and tail feathers. Obviously they didn't read the book re: the age of molting. Also, an other question to ask in relation to molting is if supplemental light is used, or any changes in nutritional status. My girls have all lost a lot of weight, for some reason, stopped eating the crumbles, though they smelled and looked fine. I just replaced with a new bag of 22% protein crumble, hoping that will help. I'm also supplementing with BOSS, cracked corn, sprouted wheat and barley. I may with-hold the seeds and sprouts for a few days to see how they do with the extra protein feed.
On an unrelated note, the loft of my coop is 4 x 8 which is closed in with an inch of insulation, windows covered with glass on north and south, 4 x 8 vent over girls favorite roost north and south, pop door under their favorite roost south. Doors and windows north and south not well sealed, so there is some ventilation around them. I'm doing DL shavings, have used permethrin and DE under litter which has obviously been scratched up. The girls are not coming out into the vinyl covered (open on the south) coop run (8 x 12) much. So, obviously they're building up some poo in the loft with smell noticeable in the morning. The poo is not capped, well scratched in. If you were me, would you clean all of the litter out (b/c of the permethrin) and start with fresh litter, or just throw a couple inches of fresh litter on top? I wonder if I should remove the glass from the south window which faces into their vinyl covered run, and perhaps close in most of the south opening of the run??? Advice? Temps down to 0F last night, high +10F today.
