Ok so I have 6 hens and currently 8 pullets. 6 of the 8 pullets were purchased at the same time and are about 15 weeks old (the other 2 are 5 weeks younger). But to make a long story short I raised 2 of the 6 pullets(and the younger 2) for a friend at about 6 weeks moved them to her house and recently during to a series of bad timeing events moved the 4 back to our house. Given I'm not really set up for 14 chickens they have a smallish coop but plenty of run space. Anyways on to my question. My 4 of 6 pullets are developing large dark pink combs (2 of then are even becoming floppy) I'm talking like close to laying type combs. But her 2 of 6 still have no comb to speak of. Given us these are feed store specials we have 2 bards, 2 reds and 2 ameraucana(EE) she had taken 1 ameraucana and 1 bard. Only main difference between my coop and hers, is the fact that I had 6 laying hens... so I'm wondering is it possible (though each pullet matures differently) that simply being raised with other laying hens might incourage pullets to mature quicker then pullets of the same age raised independent of laying hens? The 2 reds in the group were supposed to be dinner experiments but I'm already worried if hubby can't do it soon I might be rehoming them soon as new layers. I never planned on 14, we are supposed to have no more then 6 I was going to push the bar and keep 8 (my 6 hens and 2of the pullets). Hopefully my friend can take hers back soon or I'll have to re home them too. But is there possiblly a Nature vs Nurture effect going on.
