How long is the usual molting season for chickens? Our biggest Buff Orp, Margo, started the 1st week in September, and is still molting. Is this normal? Our other 2 started about 3 weeks ago. Margo's comb is pale but she is mostly filled in and seems to be acting fine. Edith and Agnes are splotchier looking then Margo, but their combs are nice and red. Their coop & run look like some one set off a bomb in a pillow factory. My concern is that our weather is taking a turn for the worse come Tuesday evening, below freezing temps and possible snow. Their run and coop will be covered with plastic sheeting like last year, but I still am concerned since this is their first molt. They were so fat and fluff last year, I miss my chubbies sitting on my lap! Any one have words of wisdom for me????:/
