i recently got chickens, 2 cochins and 3 young RIR. I notice the 2 cochins sometimes open mouth breathe when its hot.. they have access to shade and they have thier run to come out into whatever breeze there may be. i read cochins have a harder time with heat bc they are so fluffy. i dont know how i would run a fan out there if i were to.. its quite far from any outlets:/. they are all young chickens, if i keep icecubes in thier water, and they stay in the shade should i worry?
