How soon in the breeding season, can a female begin glowing? I've been palpating my female normal (I think I finally have it down. Felt 4-5 follicles today! And there was no mistaking them!) and she has 4-5 follicles(larger than a marble, smaller than a golf ball.). She's been paired with my pastel off and on (3 days on, 3 days off, though there have been periods longer than 3 days where they were not paired up). My first recorded pairing was 11/30 but there may have been a few pairings before then. She looks normal as far as body goes. She doesn't seem to be getting any thicker. She's on the warm side whenever I open the tub. I have not observed any bowl wrapping. She shed last week and today I went in to separate the two and I noticed she did look a little lighter than normal. Her neck area is getting brighter but I don't think I'd call it "the glow". I saw her glowing last season and she isn't even close to that but she is getting brighter. I was just wondering, how early a female can start glowing. I'm going to get a picture if I can, but the lighting will be bad due to its my camera phone. (unless by some miracle I find my camera)
